one thing...my heads are fully ported by Hughes. I think the chambers might be a bit big
I'm making mid to high 300s and low to mid 400s in torque. I'm real happy with that power, got 20mpg on the highway with it too!
Do you know what the cc's of combustion chambers are? When they do a port job I just thought they opened up the intake and exhaust ports?
89-91 Roller Cam 360's are a great foundation LA 360 longblock.
Advantages:
Hydraulic Roller Cam/Lifters
8.8:1 Advertised Compression....Hardened Valve Seats....enlarged pushrod holes....1.88/1.60 valves.
The Downsides of this engine:
Steel Freeze Plugs
Smog Injection Ports under the exhaust port
No Windage Tray
TBI Fuel Injection
I paid $150.00 for mine 4 years ago....pulled from a 89 4x4 Ramcharger 150....bout 118,000 miles showing , bores looked perfect......tore it down anyway.....replaced the usual Freeze Plugs, valve seals, timing set, added a timing tensioner...reused pretty much all the hard engine parts, regasketed it/sealed, reassembled it, and have been cruising along to the tune of 25,000 miles over the last 14 months....problem free.....gets 18-20mpg on the highway with 2.76's.
My buddies Accelerometer App on his I-Phone suggested that my car is putting 195hp to the rear wheels....
with a pretty stock combo..stock OE roller cam..340 Thermoquad/340 intake, 340 exhaust manifolds, 2.25 full exhaust....3400lbs
10.0 @ 82mph - 1/8

What kind of power are you looking for? Stop light warrior?
I have not dyno'd the combo. The old combo, same short block in a '73 Cuda 4spd, stock suspension, car listed at 3650 with myself at 170lbs.
Edelbrock RPM head, AG intake & 750
Super comp headers into 2-1/2 dual exhaust
Mid 12's. I can't remember trap speed.
Sorry for not being a little more exacting. It's been almost .... Well, a really long time.
S/S springs, upgraded clutch, better shocks reduced overall weight and wider tires help this combo into the lower 12's. In an A body, you should be able to do this and easier. You could be able to do this with a set up like 4.10's & a 26-27 inch tire. Still have the ability to drive around town and some Hwy. travels. A better cam can knock a few tenths off and have better drive ability.
You could up the cam considerably. [email protected] with .600 lift and feed it a dual quad.
Done right, high 500hp levels are a good and proper tune away.

stop light warrior indeed. Wanna build the car into a sleeper kinda like this one.
Going to do the calculations for a home built 3 link and when funds permit, go for a Hemi Denny k-member. It has a 518 attached but sourced an A-833 locally. the issue with that is a RHD bellhousing. And then there's the expensive clutch setup.
Car is a basket case at the moment with no running gear or suspension. I have a Dana 60 but it needs to be cut down and have new axles made.
