Have a 383 lt1 forged -5cc mahle flat tops with 208cc intake /65cc canfield heads. 238/246 @ .050".567/.567 lift (.604/.604 w/ 1.6 rockers)108 LSA m6 3.73s with all supporting mods longtubes 58mm tb ect ect.
Just wanting input on how to finish the build, should i mill the heads down? Would i be safe to add boost? I want to make the max power possible. Without swapping the pistons. Let me know what you think, my best bet would be. i dont mind running octane boost and 94. thanks in advance.


Also i will be running a ported super vic "e" manifold with the nitrous works elbow, has anyone had any exp with the msd pro billet distributor, i dont mind cutting a hole in the cowl/dash. or would it be better to stick with the opti?

 

with -5cc pistons in my 383 build, that put me around 12:1 SCR with a 54cc head. with a 64cc that'll put you around 10.7:1 SCR give or take. that wouldn't be a boost friendly build especially with that cam with a 108 LSA. I'd recommend looking into running the impy head gasket or milling the heads to bump the compression to atleast mid 11's. don't waste time and money on octane booster, either get real gas, meth, alky, etc. but as long as you keep the DCR relatively safe you shouldn't have to worry about that unless you're running a healthy shot on top, my 12:1+ SCR motor runs on 93
