Re: Bench Data
Nice work
What do you recommend for someone looking to install guides to use 8mm valves?
They would be Dart knockoffs

Re: Bench Data
All in all done with manifold. 6% loss to the front two. 2-4% all the rest.
Engine going together this weekend.

Re: Bench Data
Chad thanks for the pics, always interesting to see someones work. Wondering why those intake elbows are always straight and not belled somewhat just above the plenum, maybe shaped somewhat like a blowthru bonnet for a carb? I know some elbows for those forward facing throttle bodies have a divider top help even out front/back flow. Any insights if you have tested any of that? How close have you gotten the front and back with a converted carb intake elbow combination?SpeierRacingHeads wrote: ↑Sat Oct 12, 2019 10:32 am All in all done with manifold. 6% loss to the front two. 2-4% all the rest.

Re: Bench Data
Because it needs to fit under the hood. I tested everything on this. The front two runners have a 5.8% loss, the rest 4%. Within less than 1% of the carburetor and spacer.tt 383 wrote: ↑Fri Oct 18, 2019 5:56 pmChad thanks for the pics, always interesting to see someones work.

Something else of interest. Have a couple of Super Stock customers that run the Edelbrock elbow and a 58mm and they want me to do this type for them.
Re: Bench Data
Ahh ok, so not much difference from a carb. I figured there was a space constraint as low as it is. Thanks for the explanation and insight to limitations you were working with.SpeierRacingHeads wrote: ↑Fri Oct 18, 2019 6:01 pmBecause it needs to fit under the hood. I tested everything on this.

Re: Bench Data
nice work as usual....what kind of improvements did you see going from 2.02 to 2.08 intake on those?
Are those the cnc heads you do or the epoxied ones

Re: Bench Data
probably, but long headers and dual exhaust is a PIA in a 3rd gen unless you like it hanging down 3".
