i am building a small block 360 and i wanted to know how much horsepower a 750 holley 4bbl double pumper , 484 lift 284 duration cam and a edelbrock dual plain intake manifold with give me

 

Depends on the heads and exhaust that you have. What year is the motor and heads?

 

the motor is 1985 and i dont know what heads they are and im going to put jegs headers and dual exausht all the way back

 

you post is kinda lacking, like 78d200 said. heads, compression ratio, with what you provided. im guessing 300-315 at 5000

 

thanks but how much will it give me at 2000

 

2000 rpm, 120 130, maybe, gota know what you want to do, the right combo and you can have 450 at 5000, and 200hp at 2000

 

A good RV (truck) cam with a full exhaust and some head work might get some some extra HP and torque. I'm going to assume that you have a set of stock heads on there with no work to them.

I think Comp Cams has a small program on thier site that allows you to plug in the info about your motor and tells you what it should be putting out at the crank.

What are you going to be using the motor for?

 

im going to use it for street and play around at the track

 

What would you like to see for HP and torque numbers? What is the vehicle this motor is going in? What transmission and rear axle is backing it up? Gearing in the axle?

 

im going to put it in a 1 ton truck and i want to see about 300hp and 375torque i have a 727 torqueflite tranny and a dana 60 rear end with 4 10 gears and i am going to also put dome pistons in it

 

RV cam, shorty headers, full exhaust, some head work, and what you have already should get you close to those numbers.

 

ok thank you for your help i really appreciate it

 

Post up pics of the motor and truck build. We all lover pics here on this forum.

 

As far as the tranny and rear end goes......

Trans - install a HD shift kit that is designed for vehicles that tow (I think B&M puts one out). Also, you'll want about a 2,000 RPM stall convertor as it will really work well with the cam.

Rear axle - being a D60, you'll have a ton of aftermarket support. Find yourself a Tru Trac (posi/limited slip/sure grip) and install that. One thing that is a cheap and easy upgrade is installing 35 spline shafts. You'll have to measure the spindles to see if they can be bored out. If they can be, you can replace the side gears in the carrier with a set from a front D60 (35 spline) and then buy a set of 35 spline forged shafts. If you don't mind some tire wear, go with a full spool. Everything here will depend on how beefy you want your axle to be. Also, look into getting yourself a traction bar setup to keep the axle from rotating under heavy accelaration.

 

thats nice to hear! limited slip, i know its a ford name, but everyone around here thinks a limited slip is the same as an open rear end, (1 tire fryer)

 

You never know what people know them as so I usually post all three names just in case.

 

one more thing it has a 180 hp at the crank now i am going to put 750 cfm holley carb ,hooker headers full dual exhaust dome pistons to give me 9.5 to 1 compression then get the heads milled 30 thousands to add a little bit more compression and a mild cam with a lift of 484 and duration of 282 and a edelbrok intake manifold im going to gasket match the heads on the exhaust and intake side how much horsepower and torque do you think i will have at the crank

 

my comp cams desk top dyno says around 370 hp, but i dont know. about 350, is my guess at 5500, i was just guessing with headers and heads,
also the 180hp figure u gave was at the rear wheels
