Hot Rod Magazine HP 273 build
I thought it was interesting that the Headers only added just under 11 HP.
That's normal for a small motor and considering those 273/318 exh manifolds were designed around the 273.
Some of the expensive off the shelf headers "for most street combos" only add 12-14 hp. I'm sure if you up'd the ante and went next level...that in comparison to the exhaust manifolds , headers would yield 20+ .and so on. Basicaly stick the power range way higher up in the rpms and the increase is greater..cause the manifold cant scavenge .
Near article ..but the thing about the 273...is it's no smaller than a 360 'externally'...so the novelty just isn't there, for me at least. Like a 265 vs 283, are you really gonna choose the 265 block, hell no. I wouldn't even choose a chevy in the 1st place..lol. but hopefully someone gets what I'm saying. Unless you have a special 273 4 brl car..build a 318 or 340...otherwise go 360 or 408...more power in the 'same looking' motor. Always interested in mopar stuff ...so cool article though.
I'd actually like to see more 241 red ram builds, 3 something cid poly truck motor builds with hemi head swaps... lol how about a dyno test of the those weiand multi 2 barrel intakes on a 383 or 361.
Next time ....they should turbo it.
