I think I might be replacing my roller cam (and maybe upgrading it) since I wiped out the fuel pump lobe. Im looking to keep this as low-buck as possible, but Im not opposed to buying quality parts. Unfortunately that means no solid roller upgrades.
Heres my setup-
AFR 180 heads
Edelbrock Performer RPM manifold (side note: what can I use to fill the heat riser in the manifold? all of the gaskets I get still have a little hole that allows exhaust into the riser. Are the block off plates just as effective as filling it?)
Holley 650 DP
Comp Magnum hyd. roller lifters, roller rockers
Bottom-end is a 350 with forged crank/rods/pistons. Compression comes in at about 10.9 Block is decked, although I have to find out how deep the pistons are in the hole. I would like to get the compression and quench up with a thinner gasket if you think I can work it on 93 octane.
I have 3.55 gears, and a M20 trans. Car weighs 3075lbs with driver and full wet.
Im not opposed to a rough idle (would actually prefer one). I do drive the car pretty much every day, and sit in traffic during the summer, so I do need some power down low, but the car is fairly light, and I still have the stock (heavy!) flywheel
Heres the cam that I ran before I pulled the motor out.

It ran really well and had some great driveability, while still pulling hard up top. Im just wondering if there is room for improvement while not straying too far away from this power range. It has to be a hydraulic roller too.
Maybe recommend me a fuel pump pushrod too so I dont wipe this cam out
Thanks
