I got it done. I built a really nice 307 sbc .040 over. The intent is an all strip small cube engine. Built sheet: 081 full port Extremely worked superstock style heads. 0 Deck block. Ultra light crank and rods. 10.3:1 compression. Cam specs are .503/.523 duration 237/247 and 108 lsa. Full Port Hurrican intake. Edelbrock 1405 carb moddified. Custom 1" swirl port spacer (may come off because of nitrous). What kind of power should it make or what kind of ET's should I hope for? 86 Monte weighs 3236 with me in it (looking to get rid of more weight). Th350 3500 stall stage 2 shift kit 4.10 gears 275/60 drag radials. Starting with single stage nitrous but will hope to go to a two stage (125 or 150 then 250) later. Starting with 100 shot for now. Any Ideas. Thank you! Will try to upload pics of engine.
