402-CID displacement
Eagle 6.125" H-beam rods
Includes new, factory-installed cam bearings; Clevite rod and main bearings
9:1 compression ratio
i was just looking for some advice as to what kind of super charger kit i should get and also advice on what head and cam would go best cause the current setup that will be in the engine goes like this

If you are serious about going with a SC be sure to buy a kit in pieces and not one from ATI. Buy the bracket and built setup/ tensioner from some one like SDCE with there spring tensioned 8 rib setup.
Then do a Front mount intercooler. A D1-SC will get you there if you can stop the built slip...... if not then step up to a F1 head unit.
Then the fuel system....... be sure to plan out all the details before the grand total of $$ sneaks up on you.....

while that cam isn't ideal, it will work. As stated above, buy your kit pieve by piece. Your heads are going to determine your final compression ratio. A D1-SC will work, but if you ever want to step the boost up (which you will

ok heads are 62cc with 204intake valve and 157 exhaust valve and are suppose to flow between 305-310 i dont know what thickness the hg will be yet but i will probably switch it to what ever will work best once i get my setup correct,cause the car will be N/A over the winter,how much does an f-1 go for?

) I would get the f1, either way you'll have a monster.yes thats true i will like to eventually work up to
1000rwhp if possible but for that what heads would you recommend?i will probably use my current h/c combo while the car is NA/ then sell them and get a better FI h/c combo 
afr 225's or some stage 3 6.0 liter heads are your best bet (if your goin for best possible parts id say the afrs are the way to go). Good luck though your car sounds like its gonna be a monster!

Yep, AFR heads, or if you're planning on waiting I hear GM is going to be releasing some new big boar heads that will flow near/equal to the LS7 heads, so you might just want to wait and see. As far as a new cam goes, FI cams are tricky to recommend, so I'll just say you're going to want less overlap, higher LSA.

thanks,i was thinking of doing some afrs how much boost would it take to hit 1000rwhp? and if ne one is interested im planing on selling my stock ls1 block as a bare block or almost long block 64,456miles

ok cool thanks for the heads up i never heard about those heads till now so i guess it will now be between those heads and the afr definately
will i need to upgrde to the fast 90/90 or will i be ok with the ls6intake?

thats what i thought too but i bet with that cam the car will sound mean as hell cause with my 233/239 it sounded awesome
also what kind of rim tire combo should i be looking at?just to get an idea
IMO you should keep the ls6 and get a ported TB, the fast has been known to crack when put under a certain amount of boost, and the ohio boys are knocking on the 7 second door with an ls6 intake. If you use the AFR's you can keep the ls6 but if you use the 6.2L your probably gonna need to switch to the ls7/truck manifold.
