I like the later 72-74 Challengers !
Often categorized as "also rans" in the mopar musclecar genre, I'm completely satisfied with the option pkg's, appearance, and general characteristics of the later "Rallye pkg." cars, especially the 340 deals.
FAR under-rated for now, a good thing when purchasing.
Why are so many people convinced that the 440 is an "upgrade", when compared with building a SB based stroker with the 4" crank ?
Numbers matching issues aside, I'm of the opinion that it is "more than viable" to consider, when rebuilding, to simple build a sb stroker @ 450 hp/435 Torque, for pump fuel, and run that in the E-bodies, considering the lesser front end weight loading and handling characteristics. NO SNOW PLOWING EFFECT !
Also; NO farting with SB to BB "changes for installation", rad, torsion bars,trans, etc., etc,. and the COSTS of said changes !
"NO BRAINER" these days for me. I'll build a 360 based stroker for "bolt in" ease in my 72 340 challenger, and will be sticking the original 340 in a crate in the corner.
I've built and dyno'd a few a sb 360 based strokers, on pump fuel, aluminum headed, and solid flat-tappet camshafts, @ 540 hp/535 torque on the stock blocks. Much Higher numbers with Rollers, compression, and aftermarket blocks.
"Those", are a "bit much" for what I'd consider for a daily driver/touring deal, but, that said, I'll repeat the 450 hp/435 torque "target", SMALL BLOCK, with a hydraulic stick and ported iron heads, as a FAR BETTER option than switching to a BB.
And FAR CHEAPER overall to boot !
I ran BB Mopars for years, street and competetively, no dis-respect intended for whoever goes to the BB. "Whatever floats yer boat".
I could "whip-up" a "451" or "440" at those power levels, or higher, in LITERALLY in a "few days".
The question I can't answer "these days", is "WHY", when I can "pretty much", "just as easily", and overall cheaper, do a SB that will bolt right in and compliment the existing Rallye Cars support systems perfectly with minor tweaks ?
Just my opinions, no wars wanted.
FC out.
