Ok, here's my engine setup for my weekend warrior/mud truck

The truck is a s10 with 31" tires 4.10 rear with a locker, and a manual 5 speed.

The engine I'm looking at putting together is a 350 with Vortec heads, flat top pistons, RPM intake, retuned HEI, long tube headers, E-fan, the usual stuff...

I'm looking at one of those "IMCA" cams off of ebay. Its a solid flat tappet cam with
279/ 282 ADV dur
248/ 251 @ .050"
.531/ .542 lift
106 LSA
.016/.016 lash
2700-6800 RPM range

I know it has aggressive ramps so I'll have to be particular about springs and use special oil high in ZDDP.

also, I'll be running valves with .100" longer stem height so I won't have lift interference problems, roller rockers, and I'll angle mill the heads to get as close to 10.5:1 compression as I can with .040" quench and flat tops with 2 eyebrows on the pistons.

I really like these cam specs, but it is an "ebay cam" so I don't know if they are notorious for problems. They're also only $100 and I'm trying to build this on a budget since this is my third car that I'll have in the stable that is "just for fun".
