I'd like to hear from any 13 second cars on any combos they are willing to share. I'm prepared to assemble my 350 plus .030. I did hear from one guy Kenny but lost that number last winter. I have a 70 GS 350 342 gears fresh t400. suspension just done. I have stock 70 castings with TA stainless valves. bowl port. stock intake, TA intake. alum stock rockers. punched .030 over block. I will be using exhaust manifolds. will have A/C too. So far here I am not too impressed with the performance of these streeters except a rare few including the flying stocker cars. A 455 could fit as well as a BBC. I'd like to keep it stock looking. Any ideas?. thank you in advance, Chris
I guess I dont fit in the 13 second catagory! I was running 12.6 on the motor alone and 11.2s on the bottle. :Brow:
thanks for the reply. All I ever see here is happy 15 and 14 second cars. that to me is disappointing. I ran 15.1 at 89 a few years ago stock 350 ,stock tranny and 99 dollar convertor and 273 posi. 12's seems out of reach from my reading here. anyone willing to share info on some decent combos is welcome. I have a BBC and a rebuildable 455 which needs everything which is 5 G's in my book. I have most all components from TA and some old kenne bell .030 pistons 10.1 to 1 style with valve reliefs 750dp and what I previously wrote. what kinda cams are gonna git it done. spacers etc... thanks again chris
The powers in the heads. Send them off to Jim Burek at PAE Performance. If you're more into doing it yourself, follow this thread http://www.v8buick.com/showthread.php?t=78760
heads are done. done by outlaw machine in North Babylon on Long Island. he has put a number of buicks in the fast lane. a few 10 second 455's are running on his port work.
One of the members recently made 500+ HP with a GS111 cam from Postons and a lot of head work on 10-10.5:1 compression. I'll try to dig up the thread incase you didnt see it. Here it is - ended up around 550hp naturally aspirated http://www.v8buick.com/showthread.php?t=40660 and this guy is up over 1000hp with a super charger and basically a low compression NA build (with lots of custom parts, of course) http://www.v8buick.com/showthread.php?t=68183
Chris, Where are you on the island. We'll need to hook up. I'll get you into the low 12's or maybe better. :Brow: Oh yeah, I'm in N. Babylon.
I'll say it again, Power is in the heads. You mentioned them being done already, what kinda flow numbers did you get out of yours ? I just left Bureks shop a couple days ago and had a nice long look at a disected 350 head. Drill holes, grind through marks, everything you can imagine. He is seriously doing his homework on them, and has a head he is cutting up for knowledge. Robs NA 350 made some good numbers with a off the shelf cam and a lot of headwork. That was a 10 to 1 motor for a street car. Watch for posts by Professor Buick, he is a wealth of knowledge. And last but not least, Bill here, our fearless 350" leader in the HP range. He offered his help, I for D@mn sure take him up on his offer to help out. Good luck, and let us all know how it turns out. Seems to me there are a few more 350" fans popping up now that some guys have done some serious homework. I have a feeling we may see some VERY respectable 350" times soon.
Anyone got a ballpark number on how much Jim charges to get the heads to the point we are talking about here? Thanks
I'll take a guess here John but Jim would be the final answer. Serious port and bowl work and flow all cylinders - $1500-$1800. Just as much as the BBB. There is some serious research being done with these heads now. Long long overdue.
Yea dont have any times for you but it wont take much to run 13s. Your heads and a cam and rejetted carb should get you there with traction. Headers would definately help. Im about to do a build on a 10:1 motor and im gonna see how fast i can go on stock manifolds as well. Im looking forward to getting some work done with these heads here this week after Bill posts some pics, then maybe in a month ill have some timeslips to throw at you. Have fun.
Mine has been running for 10 years now. I have mostly TA parts on it. I have just put Nitrous on it. I just beat an 04 Cobra with charger on it with a pully on it for more boost from a roll on out of low gear. I think the 350 has lots of kahunas. Now if I had those aluminum heads and a Procharger hmmmm. :3gears:
thanks for the replys. the heads are done by Jimmy of outlaw machine. His work is well known in the LI area. He was the man of RS Competition and Vice. I did not get the heads flowed. this is a street car and I'm looking for good performance not a race car. what I usually read on hear disappoints me honestly in the performance dept. I'm glad I turned a few heads here as most reading here is the 14 15 second range. I pretty much summed up my combo here but need a cam and do these TA intakes work with ported heads and do people port match the intakes as they are like peanut port. I'll tune it no problem. just need to hear it can be done. how come Buicks use wide lobe centers. the intake ports on these 350 heads are similar to vortecs on the intake side with the little turn in the bowl. the exhaust has a big ass dog leg turn. chambers seem workable, wide n flat. look forward to assembly in next few weeks.
I know my input has been anticipated on this one :laugh: MAN!!! I have been BUSY here lately! What with work and the new farm,,, building the log cabin [have not actually started building, but plans, permits, etc. keeping me up at night], not to forget parenting and spending time [very little actually] with the girl friend. OK, enough with the excuses o No: Professor Buick says: :Smarty: Chris- You are seriously mis-enterpriting exactly how good a 14-15 second run is for a 68-72 skylark. For starters, no Chevelle, Le Mans, or Cutlass with a standard 350 ever ran that good from the factory. Plus the Buick's were the heaviest of the A-bodies, and almost always came with A/C, P/S, P/B, upgraded interiors, etc. While a plane jane stripper chevelle with a 350-2V might weigh in @ 3700 lbs. The average 'Lark usually comes closer to 4000! Something else you need to remember is that 5.0 Rustangs and TPI Camaros ran 14-15's off the showroom floor, and they are usually considered to be good performance cars. How fast is a new Z-06 'Vette? High 11's to low 12's????? And you dont think a 14 second run is good for a 35 year old cast iron land yacht with a stinkin carburetor???????? [that weighs almost twice as much!] Seriously tho, getting your car into the 13's is a piece of cake. The secret is to have a plan, and capatalize on the SBB's strong points..... TORQUE!!! SBB's make tremendous torque from just off idle to 3000 RPM's. While this is just fine for launching a heavy car off the line in street traffic, in it's stock form, it starts to fall flat as the R's rise. Start by raising the powerband up to a level that gives you performance at the RPM you intend to use the car at by selecting the proper cam. [in this case, 2-5500 R's] and then match the components to that powerband. [i.e. 2200 converter, 3.40-3.60 rear gears, free flowing exhaust, bigger carb, etc] Next, you really should have the heads flow tested, and then re-worked [as nessecary] to equalize flow thru all the ports. Even the worlds best head porters with the best of intentions can actually hurt performance by just 'hoggin out the ports without checking for flow equalization. If one intake port is flowing 250 cfm, and the one next to it is only flowing 190... Well, you might be better off running a totally stock set of heads and just tuning the engine to work with them instead of a mis-matched set of "performers"..... Finally, your going to need to get that power to the ground. A posi is a must, as is tuning the suspension for ultimate traction. Without doing that, your just going to have a 370 horse-power burnout machine. I hope some of this helps... Parental duties call, so I must go now.
Thank you ladies and gentleman, . . . Class is over for today. . . . Sorry Darryl, just couldn't resist with the whole "professor" thing
and now for some performance talk. so far Bill on LI is the one man to step up and say he's done it. Ken from LI too previously. I hope you all are not satisfied with 15 second time slips. I live at sea level and it has gotta be better than this. I don't plan on flowing the heads. each port ads up to to much for me.
I am ready for my 15 second time slip! But I am only speculating my motor will run that number it may be a touch faster but I will see soon as my motor is finished :Brow:
