Hey guys , found another mustang here but looks like someone put a Chevy engine in it ? The vin says it should have been a 351 ?? Q code ??
Well the Ford motor with it's front mounted distributor and oil pump doesn't place torsional loads on the camshaft effecting cam timing the torsional load from the valve springs doesn't effect ignition timing. Exhaust valves aren't placed next to each other. The Ford uses a larger diameter valve tappets which allows better cam profiles. The 4/7 swap Chevy guys discovered is the same firing order Ford has used since 1932.Chevy small block using modified pickup truck brackets(mid 90s+ brackets). There used to be tons of them at the super chevy shows. Still the best engine platform out there. Sorry diehard ford guys...

The LS motor has more in common with the SBF then the gen 1 SBC. The LS heads will physically bolt onto a Windsor block. The valve and pushrod spacing is the same. The kit GM sells to use a mechanical distributor and fuel pump actually uses a Ford distributor and fuel pump.

actually the firing order is the SAME as teh early small block ford, you are just forgetting that cylinder numbering and distributor rotation are different. make a diagram of the small block ford firing order, then renumber the cylinders and change the distributor rotation, and you will find i am right. i learned this 40 years ago.JoesephQatar, its all that heat and sunshine out there. Bakes peoples brains and they don't realize they have sinned a great sin.
Elcam, you sir, are grossly misinformed. The classic small Chevy is a disaster. The firing order is wrong, the lifters are too small, and the center exhausts are right next to each other with no cooling in between. Not real smart. And, interestingly, the newer LS Chevy appears to just be a GM built 351W, I'm certainly not impressed. LSG
it wasnt about the roller lifters, but rather the flat tappet lifters. the larger ford lifters allowed for high lift and shorter duration cams before the edge of the lifter would dig into the cam lobes. the difference was enough that the racign sanctioning bodies allowed chevy to bore out the lifter bores to the same size as the fords so the chevys could run similar cams.Never seen or heard of any issue with lifter diameter.
i agree with blake on this. i have great respect for the small block chevy, having owned a few in my lifetime. they have plenty of parts support in the aftermarket, in fact even today new parts are first developed for the small block chevys regardless of generation, ford comes in second.I don’t understand the armchair engineering superiority. The SBC resume is beyond impressive and evidence of its accomplishments is everywhere.
Better is some ways, worse in others and deserving of respect.
My friend's 29. He has a Red Ram and Nailhead squirreled away for other projectsWhen I go to the car shows, I appreciate the guys that, after doing a nice car, don't cheap out on the engine.
Instead of dropping an LS or SBC in, because it's cheap. They spend a whole bunch of money making a car really nice then take the easy or budget road on an engine.
Seeing a guy that keeps a nail head in a Buick, doing a big block olds or Pontiac, a Chevy 409 trumps a BB or SBC, dropping a 392 hemi in an old hotrod or rat rod is way more interesting than a SBC with chrome valve covers. Seeing a hopped up flat head ford, great.
Even seeing guys that tweak and rework the inline or slant sixes, that's cool.
Seeing a paxton on a SBF or Webbers = cool
Doing a Cleveland or Cleavor = interesting
Honestly I see all kinds of old street rods at the local shows 99% of them have a SBC with an auto trans in them = boring
See a guy that hot-rodded a Cadillac engine, and stuffed it in a rod = cool
I had a 340 W2 motor years ago, that would leave virtually every SBC and company in the dust. The only cars that would be trouble were the BBF's 440's and 454's
Not saying there is anything wrong with a SBC in a car it belongs in, but if I see two Camaros, a Buick, Olds and a Firebird lined up, I'm gonna spend the least amount of time bothering with the 350, and spend more time looking at a 396 Camaro, Pontiac, Olds, or Buick.
It's the vanilla ice cream of engines.
at least one way, for instance the distributor in in the back of the engine causing greater torsional loads on the cam shaft. another is both blessing and curse, and that is the way the oil pump connects to the distributor shaft, with a blade type connection like a standard screwdriver, and a collar to hold thing together. also the distributor mounting area has TWO gasketed surfaces allowing for a greater chance of oil leaks.BS! You can't name one way that it is worse!
