So roughly 6 years ago I built a 355 for an old truck of mine. Had stock bottom end with l2256f speedpro pistons, 062 vortec heads, xe274h camshaft, and a performer rpm intake. Truck ran extremely well! Anyways I got in an accident with the truck so it has sat for a couple years. Went to pull the motor out and found out it’s stuck, water got in it somehow. So now I’m down to building another motor, but planning on having an another block bored .030 so I can use the .030 pistons out of the other motor along with the camshaft. So here are the parts I got so far
-New eagle cast steel crankshaft (old one didn’t look very good)
-stock rods with ARP bolts
-l2256f speed pro flat top pistons
The lower end has been balenced
-xe274h camshaft (487/490 lift 230/236 duration at .050)
-promaxx freedom series heads (64cc chambers, 185cc intake runners, 2.02/1.6 valves)
-comp cams 1.6 roller rockers
So with all that being said here are my questions.
1. What intake/carb set up would get the most out of this setup and not effect drivability or reliability? The old motor had a edelbrock performer rpm and a 1406 edelbrock but I think this motor might need more. Am I wrong?
2. What head gasket thickness would you guys run? My gasket set came with a .038 compressed thickness gasket but would like to go a tad tighter to get the compression up since aluminum heads are more forgiving with compression and the crap pump gas we have to run.
This motor will be going in a 67 chevy 4wd truck with a Manuel and 4:10 gears. Plans are for a daily driver/ weekend puller on occasion.
Thanks in advance for any input
