Great advice going on here.
IMO, use the Comp HL series cam because THAT series cam takes full advanyage of the .904 lifter or go to Huges for one of there cams.
Get the cam with a duration to match the cars driving rpm. It works in conjunction with gear ratio and tire size.
Then get the cam with as much lift as the head can handle.
1.5 rockers!
Fle_pro makes a .039 thick gasket. Better yet, get a comteic in just your spec. .040 is a good thickness.
IMO, I'd do a 750 cfm and remove the choke and put an extreme aircleaner on top w/ an K&N stub stack. I have had good workings with this combo. Hood clearance could be an issue to get it to work best. The stub stack likes some head room.[/QUOT]
I think I like the Comp 275HL. I want to run 3.91 axle gears & a mild stall.
Drivability is a big factor to me. This will be my son's daily driver.
The ".904 lifter" you refer to, can you enlighten me?
I'm not new to engine building, but way back in "72" when I had my 340 Dart 4-speed, I hadn't delved into the engine.
I'm new to the technical side of the SM Chryslers.
