I was surprised after looking at Edelbrock castings for so many years. Some were really terrible and didn't fit correctly.ChopperScott wrote: ↑Tue Jan 10, 2023 8:28 pmWhat surprised you concerning the quality of casting?
I'll head out to the garage and take a few pics.

Re: SBC Intake Manifolds: Creating Another List.
I haven't handled enough Edelbrock manifolds to make a comparable judgement. I've read that the later Super Victor 2925 is a much better casting. As far as Holley is concerned, I can't say I'm too impressed with the castings out-of-the-box, but with a little time and effort, they could prove to be nice pieces.rfoll wrote: ↑Wed Jan 11, 2023 9:30 amI was surprised after looking at Edelbrock castings for so many years.

Re: SBC Intake Manifolds: Creating Another List.
He must have let off the throttle on that run buy the 1/8 to 1/4 mph. Nice time though.ChopperScott wrote: ↑Mon Jan 16, 2023 11:30 amMike is proficient at tuning Holley EFI with nitrous.

Yep. By my reckoning it takes about 3 seconds to cover the eighth mile at 145 MPH.

Re: SBC Intake Manifolds: Creating Another List.
He definitely cruised to the 1/4. It would have spit out the bottom end if he stayed on the throttle. He tells people it's a 327.

Re: SBC Intake Manifolds: Creating Another List.
I didn't want to give up on the Holley 300-110. Even though I tried it with two sets of 1206 gaskets (2 x .060), I decided to order a set of of 1266 gaskets (.120). After further inspection, I'm confident it will work. I will just need to be careful with the roof on the one set of runners when matching.

Re: SBC Intake Manifolds: Creating Another List.
That intake works great if you want your TQ to peak higher than your hp. For his procharged methanol deal, it won't matter though. Might actually help.ChopperScott wrote: ↑Sat Jan 14, 2023 7:01 pm This is his current intake manifold...
