Just thought I would share some results on an engine on the dyno right now. The combo is sealed power forged pistons, total seal rings, KB cool runner manifold, 1000 demon, ta stg-2 alum heads flowing 317 intake and 260 exhaust, ta 290-08hl cam with 1.6 roller rockers. Actual compression is 10.1 to 1. How does 590 at 6000 rpm horse sound and 570 torque at 4600 sound? This is only the 4th pull on the engine. Have'nt even started playing with it yet. It is still climbing in power at 6300 rpm. Jim Burek P.A.E. ENTERPRISES
Jim, i want to step up to THAT CAM from a 113a, i have ported S1 heads, most work in bowl blending and unshrouding, springs were set at 300lbs at 520 lift, port matched,sp1, 1 7/8 headers, going to use my good steal 1.55 rockers, also 11 to 1 compression,373's 4000sp. do you think i would see much E.T. INPROVMENT?? or diff. cam recomedation??
I'm running a 113A cam in my car. If you like, we could go over our combo's and see if we could get your car down into the 11's. Our engine's sound similar, but I'm 400 lbs. heavier and still squeaked into the 11's. Let me know or pm me. Phil
I really don't know if the cam change would net you much power wise, the 113 a is a 232/246 at .050, it has about 13 degrees of overlap at .050 as opposed to this cam which has 22 degrees, there would be some power there. The higher lift would help you somewhat, But I know TA recommends roller rockers with the HL cam. I don't know what your heads flow so can't really say what would be a good choice for a cam. As has been stated many times before, More important than what cam you have is the heads. Really good heads will make power, even with milder compression and camshafts. As this engine demostrates as otheres have done as well, with good heads, 600 horsepower is not that diffiult to achieve with only 10 to 1 compression and a not too huge cam. To hear this engine idle, you would never expect it to make the kind of power it makes. Jim Burek
Jim, just wondered which brand hydraulic lifters you're runnin? They really seem to hold up well to the lift and RPM. Thanks, Steve Walsh
This one has TA cam and lifters. The previous engine on the dyno I had was running a comp cam 255/265 and had Poston lifters. It also pulled through 6400 rpm. That engine made 560 horse , it was 11 to 1 but had iron heads. The one difference I noticed was that the first motor has lifter tick on start-up, goes away within 2 to 3 seconds, this one does not have the lifter tick on start-up. These are the ball type check valve lifters, the others are not. Jim Burek
Jim, What are the specs on this cam? I am interested because I am also running the T/A stage 2 heads with 1.6 roller rockers but my actual compression ratio is about 9.6:1 - would this cam be good for me. How streetable is this setup?
It should be plenty streetable, this cam has been reported on several times before. The full specs should be on the TA site. this engine will have mild street manners, but be a real beast when you get into the throttle. This kind of horsepower is crazy on the street, butin a good way. Jim Burek
Well it looks like the final numbers are 605 horsepower at 6000 rpm and 576 torque at about 4700 rpm. Definately a pretty stout combination, especially for a really mild engine. I think the customer will be happy with this little puppy. Jim Burek P.A.E. ENTERPRISES
How long do you figure something like that will hold together? Since you admit that a short fill or girdle would be a good idea, I have to wonder why it wasn't done? Seems to me 600hp is pushing your luck without some block reinforcement. No pricing? Jeez, one of the "other"p Buick shops posted an itemized invoice for an engine not too long ago. They don't seem to be afraid to put it all on the table. Why the apprehension?
Give Jim Burek a call as he's one of the many people that are willing to give a boat-load of information for free for whatever problem you may have. You couldn't ask for a nicer and well knowledged Buick guy to help you out.:TU:
According to some of the stuff I have seen, there is a touchy vendors war thing that could be one of the reasons. Depends on whos eyes you look through though I guess. If one person mentions prices then its just fine.......but if another mentions his prices, then its all of a sudden a vendors war. Ain't too many secrets if you just ask the right questions to the right people. Myself personally, I have learned !!! Before I make a decision on any vendor, I have made myself call, at the MINIMUM, 3 people that I would consider "big players" in the Buick world. Call them up, ask for their opinions on person "x", for whatever kinda work, and see what they say. It doesn't take long and you have a phone book full of people that you can call for certain things. And if you are BRUTALLY honest in your questions, you get brutally honest answers. Be prepared though, you may not like the answer you get. I didn't !!!! Recently................ But at least it was honest. later.......................
