I have most of the stuff already to do it but I need opinions/guidence on the intake.

1. Which intake: Super Victor or Victor Jr.?
2. Mod the intake or drill the heads for the bolt pattern? I am leaning toward drilling the heads as that is something I could probably do myself but I have not read or heard much of folks taking this route.

Please don't turn this into an EFI vs. Carb thread. I have read my share of them and made my decision.

This will be a stock bottom end build (only 64k miles) with either a LE2 or AI200 top end.

Thanks!

 

Super Vic offers better fuel distribution but requires more cowl hacking (assuming a 4th gen car here) and more rpm or displacement to use effectively. Vic Jr. is a little shorter and still makes good power. Either will require an aftermarket hood and you'll probably lose your wipers with a carb either way you go.

I'd mod the intake personally. You need to remove the coolant cross over passages anyhow which will likely require the flanges to be surfaced once they are welded up.

 

Car is a 4th Gen and will be a 90% track car. Trimming the cowl area is not an issue...neither is the hood.

Still interested in modding the intake vs. drilling the heads. I know you don't need to remove the water neck but you do need to weld and re-drill the holes. That is something I have to pay someone to do. Drilling the heads seems a better option as I can swap to either type of manifold if I want in the future plus, if I choose to go SBC someday, I do not have a single plane that I cant do anything with.

I would like to hear from folks who have done it both ways.

Thanks!

bowtie intake .. not a direct fit ?

 

The GM manifold is a dual plane. I am going high RPM and HP...well beyond the capabilities of the GM manifold.

I'd drill the manifold myself....but it really doesn't matter which you do.
