Hey guys so i just swapped a la 360 into my cuda and was wondering if anyone could give a rough estimate on horsepower that i would be pushing.

the mods are
Holley 750 cfm carb
edlebrock highrise rpm intake manifold
218/224 comp cam
msd blaster 2 coil and ignition box

also then what gas should i be using and are there other mods i could do to get a bit more kick out of this motor

Thanks FABO
 
That's a Comp XE262H, right? The regular RPM (not air gap) would probably be better (assuming that you mean you have the air gap when you say high-rise). With what you have, I'd guess around 280-300 HP tops. If it's an air gap intake, you might have a "flat" area under 1500 RPM, since it's not really a good match for the cam. Regular pump gas is all it should need, and using high octane probably won't do much for it. Really, with what you have, I think a Performer with a spacer would work best.
 
ya its the airgap intake and wow i thought it would have way more than that but thanks for the tips guys im trying to build the best motor i can seeing as this is how i bought the motor

Click to expand...

Flat top pistons and better heads to increase compression and flow would be a much better start than carb and intake.
 
where are good places to buy parts for these motors i cant find anything locally around me i assume id have to buy online.

What should i be looking for parts wise aka kind of heads, pistons etc.
 
Bout the same power as a stock 73 340.
 
I'd guess 250-280 depending on how well it's tuned

Dodgeboy summed it up. All LA 360's are real low compression. Mopar rated them at 8 to 8.5 to 1 but when checked you'll find most are in the 7's due to lousy machining tolerances. And that cam is real small but it's a good match for a real low compression engine. Now don't think it's gonna be a dog just cause it's not real high hp cause 360's, even low compression ones are known for good torque. I've seen 3400 lb. A-bodies run mid 13's with a setup like yours.

Where to buy parts:

Summit, JEGS, Hughes engines, Mancini's, IMM engines, MRL performance just to name a few

One real easy way to up the hp and torque is a head swap. The RHS heads (available from many sources such as IMM engines, MRL Performance, Hughes engines) will bolt right on, use stock rockers, and gaskets and offer a real nice improvement due to increasing the compression and air flow. Gotta have a good strong bottom end though or it won't last long.
