hey guys just got a new 350 for the chevelle suppose to be runnin pretty hot forgot the specs sheet at the guys house when i got it but I no its runs 11:1 compression. Motor is pretty stacked only this stock is the bore and stroke, has vortec iron heads with alot of flow work and a pretty big cam(have to run a 3500+ stall) Builder expects it to put out over 600 at crank but if I want more can I slap on a 144 superchager and run it on regular 91? or would i have to switch to higher gas?

You would definitely have to switch to higher gas with 11:1 and iron heads.

blower + iron heads + 11:1 + pump gas = bang bang ker-plunk ker-plunk ****!!!!

not to mention it sounds like you have a pretty radical cam you'd just be blowing fuel right out of your engine because of the amount of overlap that cam probably has

u either gotta run reallly low boost and high octane gas or run it on alcohol.

Wrong combination. You would be working against yourself. E-85, ethanol, or low low boost would be a quick answer.

Wrong combo, if anything put it on the bottle honestly. For that kind of compression you will need the expensive gas or really low boost and it will be pretty pointless.

I say bottle.

i agree, bottle or drop your compression to 9:1

If your going to run a blower you need to drop your CR to b/t 8.5 - 9:1 That would be the MAX that I would run... Look for some good dish pistons. w/ that high of CR you'd be in the shop more than on the road fixin it!! my .02
