currently run a 355 with
factory 2bolt block with arp studs
cast crank
pro tech h beam rods 5.700
trw l2304f30 dome pistons
comp 280ar roller 110 lsa 236 236 550 550+1.6 roller rockers
old style afr 195 heads 74cc
victor jr
plan on running a D1SC with no intercooler looking for 700 rwhp
plan to change to
eagle/scat 3.750 4340 crank
upgrade block with splayed 4 bolt mains
je/srp reverse dome looking for 8.0.1 to 8.5.1
750 blow through carb
can i use the current cam or does it realy need a 112 114 lsa
and more exhaust duration cam

I built a 406 for a friends car. 8.7:1 compression, Vic Jr. heads with mild porting, hydraulic roller with .600 lift and 242/254 @ .050 on 114 lsa, 750 blowthrough (later switched to EFI), D1SC at 15 psi, 91 octane, water injection, no intercooler and made 700 rwhp. I think that cam will hurt you trying to reach 700 rwhp. It's a bit small on the duration end, and the narrower lsa will make boost come on slower. You will also need water injection probably if this is a pump gas deal, unless you can get real good pump gas. On the 91 octane we have to deal with in California at that boost level we had to pull a lot of timing, which absolutely killed the power. The water injection got us back up to about 30 degrees of timing at 15 psi, world of power difference.

thanks jody your old 67 nova has inspired me to try this conversion with the stock front clip on my nova
have been thinking about water/alcohol injection
we can get 97 octane at our pumps over here
about $8 bucks a gallon

that motor is the one that ended up making 700 rwhp in my friends 69 Camaro, after some more boost and cam swap, along with a bit of head work. 97 octane gives you way more leeway than our crappy 91, but water injection is still a good idea to absorb the excess heat in the chambers, especially if you're not using an intercooler. I run it on my intercooled twin turbo LS2, and virtually any pump gas forced induction build I do, even my Duramax.
