SRH 2892
I may have asked this already, so don't dog me out too bad if I have.
I have a bracket 434 SBC shifting at 7000. It has stock Dragon Slayer heads on it and a 261-268 at .050" solid roller cam in it, with 12.5:1 compression, 1 7/8' headers, and running on VP 113.
It has a stock 2970 and a stock 1050 Dominator on it. It runs pretty good with that setup on it.
I have a fully ported SRH 2892 for a different engine that has had the works in terms of heat barriers and oil shedding coatings and all that done to it, and a vey nice 950 4150 carb.
Would it be worth it to try the fully ported 2892 over the stock 2970?

Re: SRH 2892
Did you at least ask Chad? He knows his products better than anyone and could tell you what to expect, I'm sure. I assume that's what SRH means, anyway.

Re: SRH 2892
Just out of curiosity 408Nova what kind of ET are you running with those heads and at what weight?

It is Chad Speier's work, and he did a great job by the looks of it. It's burr finished.
5.80's at 116 at 3090 lbs in the eighth mile. There might be a little more in it because it's a little lean and no timing loop has been done yet.
Re: SRH 2892
5.80's at 116 @ 3090 would take 775 hp I would't think there is anything left on the table.

Probably see minimal change either way you are maxing out the stock heads.

Re: SRH 2892
I'm thinking this thing would be very lucky to have 600 hp steve316? And that is on a good day. The engine was in an S-10 that weighs 2820 with a full fuel cell and I weigh 270.
It's going in a 68 Nova that weighs 100 lbs less. Maybe that will help it ET a little better.
Re: SRH 2892
I'd like to get the heads and intake out your way this winter to help them out some.WeingartnerRacing wrote: ↑Thu Sep 05, 2019 10:06 am Probably see minimal change either way you are maxing out the stock heads.
Re: SRH 2892
Wallace has it at 625-650... that seems more realistic408 Nova wrote: ↑Wed Sep 11, 2019 6:08 pmI'm thinking this thing would be very lucky to have 600 hp steve316? And that is on a good day. The engine was in an S-10 that weighs 2820 with a full fuel cell and I weigh 270.

Re: SRH 2892
My guess may have be off at 775; so I went to wallace 1/8 mile cal. and it had it at 762.
Re: SRH 2892
Maybe I'm missing something here. Even 600 "observed" would take a world class car and effort to run those ET's at 3090. I agree with it likely being around 580-620hp(corrected) engine by looking at the sum of the parts. But I just don't see that running 5.80's at that weight. Maybe I need to reread.
Re: SRH 2892
Na car will run 22-25 mph out the back door over 1/8 mph, if geared for it.
140 mph traps at 3090 weight is 650 hp.
Wallace 1/8 calc is off imo for a na car. I think its assuming much more gain in mph in the top end if you compare 1/4 calc to the 1/8. For my turbo car that gained 35 mph on the back end, its pretty close

Re: SRH 2892
Can I ask what gear, converter, trans, and finish line cross rpm it has currently? Thats impressive....
