I`m looking hard at the 67002 cam, however I`m curious about the different ramps and the effect on the idle. I would like to retain the luxury/ muscle car feel and not be shaking my car apart at the stop lights.
Right now I'm using a Crower cam #50258 (.446/.468 & 210'/220' dur). Not bad, but its not overly agressive. It sounds like it has decent lump to it, but I am seriously contemplating a swap to a TA310... I'm using the factory rockers, do you think it would be a good swap? What sort of changes would I notice? My brother seems to remember putting in about a 2800 stall converter. He can't remember since it was a few years ago, before I purchased the car. I will be putting in a 3:73 posi as soon as the snow melts and I can get the car out of the garage. Craig
Yep I think so too Specially in combination with a good port & polish job on the heads and intake. And or course the correct stall converter and rear gear ratio. I just hope it has some decent street manners. I'm looking for low end torque mostly in a new cam for my current build. High lift not too much duration. Kinda interested in the TA 290-94H aswell. I hear that is a very neat cam too.
Just got my cam from Camcrafters: 262/262 adv. duration 212/212 @ .050" 112 separation 110/114 centerline .436/.436 lift In. open -4btdc close 36 abdc Ex. open 40 bbdc close -8 atdc I don't know why Charles put the minus marks in there, other than it's the overlap, and those numbers are at .050 also. But I ran the specs through Pat Kelley's DCR calculator and ended up at 7.9 which should be OK for premium pump gas I think. Might not look like much of a cam for higher speed work, until you consider that the motor will be running a blower just to enhance the top end. Then it starts to make some sense I think. The blower will overcome some of the deficiencies in the intake tract and the cam and keep the power up. This is a street engine. It's not a race motor and may never even see a drag strip. All it really has to do is put out 300 hp and I think that will happen. That gives me an 8:1 ratio on the weight and I'm happy with that. With that goal achieved the next objectives are economy, driveability, and flexibility as well as extending the operating range. I think this will be a good grind for those goals, at least I hope so.

Hi Jim, If all you wanted was 300 HP then I think you have a little overkill to deal with. My 340 is done and goes in tomorrow (yes, I'm late... I know) and it should be just over 300. My best guess is that it should have about 310 hp because: I went with the TA 284/288, 223/230 at .050", 0.460 lift, 110 lobe separation and 6.5 overlap at 0.50". I have more data on it but I'd have to go find it. Sanderson Headers, shorty but better than stock. Mild porting on the intake and heads, just to match the gaskets. I was very surprised at how much I had to work on the intake, it was off a mile. Carter Competition 625 CFM carb (early Edelbrock 600 CFM). Basic balancing and oiling modifications MSD ignition system and modified Buick dizzy with MSD pickup. Duel 2.25" exhaust w/ Flowmasters and X pipe. Should be fun but it will be a long way from an 8:1 power to weight ratio....
anybody have a video of the TA310 or the TA290-94H? just curious as to what they sound like. thanx Scott
i have the 310 in my motor with better than 10-1 , ported heads and all the other good junk and it rattles the whole car. Goes reall good but not untill 3k or better...really need a stall converter or you will not be happy. Also doesn't realy idle very well under 900 or so...but at the stop lights the whole world knows its something...I get asked all the time if it's a big block
Drew that sounds like a real nice combination. Don't know how far over 300 you'll be with that but should be a handful. I think you'll have a whole lot of fun with it. And you know what they say, there's no kill like overkill. I'll just tell those smarty crate 302 guys with their "375 hp" motors that mine puts out 300 or so... and see what they think of that. I hope I didn't overdo it on this cam. I don't want a lumpy idle and an engine that won't run below 1000 rpm. I've done that already and while it was fun, I want a nice smooth quiet engine that rampages when asked to. Not much to ask from a 340 in a 2400 lb car. I dunno, everyone was saying a 340 was too much... until I started the build of one with a 455. Now they sort of just shake their heads in disbelief. But they all want to see it run, you can bet on that. Jim
I use a 260H Comp Cam 212 Duration .454 int/exh Why... because I didn't know any better at the time I bought it ou:
do you guys think it's be pretty easy to get say ta or poston or even lunati to do a custom grind with ls1 fire order swap? 1-8-7-2-6-5-4-3
buick 1-8-4-3-6-5-7-2 4-7 1-8-7-3-6-5-4-2 2-3 1-8-4-2-6-5-7-3 (bank to bank) ls1 1-8-7-2-6-5-4-3 (4-7 & 2-3)
So i guess i am the only guy who bought one of the new TA roller cams. I cant even put it in my engine because they haven't made a cam button for it yet. my machine shop has put my engine on the back burner while TA figures out what they are going to do. I wish i had known more about this before i laid out $800.00 on a cam thats not ready to be put in.
yea that sucks, that just made me more happy that i cancelled..got to pay off bills and put some cash on other things towards my builds
