hey, I'm looking for a cam for my 355, and I was wondering what you all thought. specs are...
-1973 350 block bored .030 over
-1970 LT-1 heads (487 casting number) opened up to 2.02 and 1.60 inch SS valves, polished ports, Milled down .020, cast guides
-9.3:1 compression ratio with heads, alluminum hypereutectic pistons
-Weiand High Rise intake
-Mallory $170 distributor, with the high output coil
-MSD Super Conductor Wires
-Accel Header Plug spark plugs
-Shorty Headers, and custom dual exhaust all the way back
-holley 4160 series carb, 3310 750 cfm vacuum secondaries (yea I have the quick change secondary spirng setup) also have .110 needle seat assemblies
-Holley 85 gph mech fuel pump
-Melling high volume oil pump
-electric radiator fans
tranny is a turbo 350, with a B&M shiftkit, and ratchet shifter, stock stall torque converter
for my current cam and rockers
222/222* @.050" .447/.447" lift w/ 1.5 ratio rockers... it's the 327/350hp camshaft i think it's cut on a 114*
I was looking at the comp cams XE 284 cam
Grind Number: CS XE284H-10
Valve Lift with Factory Rocker Arm Ratio: 0.507 int./0.510 exh. lift
Advertised Duration: 284 int./296 exh.
Duration at 050 inch Lift: 240 int./246 exh.
Basic Operating RPM Range: 2,300-6,500 RPM
Now I can change the torque converter if necessary but I dont want to go over a 2500 stall, if i need more compression I will drop the head gasket down to .015" thick gaskets from the .039"
but I was curious about what you all thought about the combo? an extremely similar combo was built with the same compression carb intake heads (kinda my heads have bigger valves) exhaust etc. just had the original LT-1 cam and it hit 376hp thing is with the lt1 cam i'd need the corvette's 3000 stall, which is a bit high for my driving. however I would like at the least 350hp out of it, and btw it's in my 84 firebird.
Thanks for your input
