I have a factory inline street hemi intake manifold that's going on a mild stroker hemi...500+ cubes, 10:1 compression, mild roller, etc. It's going to have a pair of Carter 9755S 750 cfm carbs on it. The car has 3.54 gears and is a 4 speed.
The manifold is unmolested. I haven't mocked it up yet, but it looks like I need to enlarge the front bores in the intake for these carbs to fit. Anything else I should do? Seems like the Vanke mod isn't a good idea for a street car...this car is 99% street driven. Any advice?

With 500 cubic inches I wouldn't think torque would be an issue so drive-ability should be fine.
That's what I was thinking too, but I've read a couple different things online saying it wasn't a good idea for a street car. I don't see it being a problem since this motor will have a 4.25" stroke in it (not sure on bore size yet). I'm asking here though b/c I have zero experience w/ this manifold and wanted to see if anyone has done something similar.

Back about 1990 I took off a stock Hemi intake and installed a Vanke modded intake on a "Fresh" stock 426 Hemi. I noticed a small amount of bottom end torque difference but not so much that it was any problem with drive-ability.
I had the mod done on my intake on my 572 but I haven't fired it up yet much less driven it but I don't see street drive-ability as an issue.
Kayse can't keep up at all now. lol
