How much HP to expect? SB

360 .030 over tq plate honed, moly rings
hydraulic flat tappet 231@.050 .583 lift single pattern
2.02 mild port job 5 angle valve job R/T heads 270@.550
M1 single plane
900 CFM CS T-quad
1 5/8 hooker headers
11.3 compression


What kind of crank HP/TQ to expect and what kind of ET from a well set up #3200 race weight A-body?

I'm thinking it "could" come close to 500 HP, depends on a lot of factors but 480 should be easily within reach.

Maybe 450 hp at the crank - I dont know whos bench flowed the heads at 270, but thats really aggressive for a mild port job right?

I'm at 400 hp at the crank with a stock set of 1.88 587 castings, 9.8:1 and .474 lift 232 dur cam

It was a local guy, that is only about 12 cfm more than Ryan J got from a stock set

ET is going to depend on the chasis...converter, gearing and tires..

That's a lot of lift for a juice f/t. Could make 460 ish with really strong torque above ~3600

Be fun in a lighter car with 3.91-up gears and a 9 1/2" vert

i am going to low-ball it and say 430hp at the crank. The 1 5/8 tubes are going to kill your HP IMO

Do you plan on putting it on the dyno? If so I'm interested in the results. I'm using a set of Brian@IMM RHS heads, m1 single plane, Solid cam with around the same lift as you in a stock stroke 360. I just have to get around to getting the correct thickness head gaskets and a few other little things and then it can be put together.

Dave, seems that your leaving a lot on the table with the cam & small tubes

True about the 1 5/8" but ( as in my own case ) they FIT and they're cheap :-). My 414 runs 1 5/8 because I know they fit my unique chassis...and FAST cars run 9's and low 10's on manifolds and 2 1/2 " pipes

I already have the cam and headers so they will be sticking around. I have all the stuff for the short block and the heads. The only thing I do not have is an intake, bearings, and a few gaskets.

I will be driving it on the street also so I probably would not make the cam any bigger if I could and If I had a choice about the headers I would probably use 340 manifolds instead. The only other exhaust option I have is 273 manifolds.

Who cut the cam? That's a bunch of lift for the 231 at .050 duration. It's more like a hyd roller set up with a 1.6 rocker.

I have the same cr, but with 244@ .050 cranking psi is at 205. Your going to need hi octain, 440 hp

Engle cam specifically for mopar lifters with 1.7 rockers.

I originally had it ground for a bigger engine with a tad less compression, then I had to sell my stroker short block. I hope it is not too lumpy for this combo

1.7's will get it there!
