Thanks for the replies guys, I knew they were pretty large for say a 350, just wondering if they'd work on a weekend warrior. I'm looking at heads for my 355, I've got forged .100 dome TRW pistons and the lower end is a fresh 4 bolt main. Haven't bought cam or heads yet. I just picked up a Offy dual quad setup last night with 390 holleys so that is the intake I'm going to run.
I'm going to install this in my 82 S10 with a powerglide, 3200 converter, and 4.11 rear gears. I just want something to tinker on this winter so I'm trying to gather all my parts.
Any suggestions, Comp Cams suggested cam 12-250-3 240/246 duraton, 507/510 lift 110 LSA. Still waiting to hear from Lunati.
