I would like to have some help in a decission on what type of heads and camshaft combo that will work.

383 cuin

Enigine 350 2 bolt block -74 030 bore

4bolt splayed caps.

Crankshaft 3.75 stroke and 5.7 Hbeam rods.

SRP dome pistons ( 12.9:1 with 64cc heads )

My goal is 650 HP below 7500rpm

If it will work with 23degree heads i would be glad ( beacause its cheper)

And to the MekRollCam it should have a lobe spearation of 110 or greater because i would want to spray i with a small amount of N2O

will this work... Canfield 220cc heads with 65cc CNC chamber and a Compcams 12-817-9 camshaft ( lift in .739 ex .693 dur in 274 ex 282 lobe sep 112 deg )

It will work.150 shot of N20 will give you your 650 h.p.Is this a pro street car or strip car?The reason I ask is the lift on your cam is a lot.If it is a Pro street car cut the lift back a little your valve train will thank you for this.Try to stay around .625 lift.It will be much cheaper for you in the long run as far as valve springs and valve seats.
