Still havent got the engine back together, need to get the exhaust fixed, and would LIKE to get the windows tinted soon...oh well, will proceed as $$$ flows in....which is a TINY flow...lol

[Dave84]

Shouldn't that car have been fuel injected if it is a '91?

[Nathan in MI]

It's a 351W, not a 302. No EFI for us 351 guys.

[351wcrayz]

yep, I like me fuel sucked....lol
how Much work would it be/whats the highest Compression Ratio I can run in the can w/o the engine knocking w/ 87octane...?

edelbrock 500cfm performer 4bbl carb

Sounds pretty small for the heads, and possibly the intake you're going to get. Nice P72, glad to see more of them popping up. How are your inner UCA bushings with 400k miles on them?

Install a vinyl top on a slicktop?!?!? Noooooooooooo!

5.8 = Carb
5.0 = EFI

1991 5.8 P72 was probably the last carbureted car sold in the U.S.

[351wcrayz]

haha, last O' the mohicans eh?.......j/k

as the engine is pretty much stock, 'cept for the carb, etc, I really dont know bout them there bushings, but I guess I will when it wont run....lol

After I get the new job and save some $$$ up, bout 2 months, I am gonna have the engine either revamped OR get a frsh crate engine.....idk, jus have to seewho the $$$ flows in...

oh, I was told by a fellow that races stangs an the like, told me that I could keep the 2.73's, and just shove alotta torque into the engine, and the gears would keep everything in the high rev range stable, an the HP an TQ would take care of the lower range stuff, any exp. on this?

Yes. Picture your rear end bearing caps on the ground behind your car. With lots of other various bits and diff fluid. Makes a horrible noise, too.

So an 2.73:1 8.8 locker with the appropriate housing reinforcements still won't handle big holeshots with a really small converter?

[351wcrayz]

So...whats the best way to get oober torque, w/ no REAL mods (Boring cylinders, etc....) and IF I DO change the rears, will I need to re-calibrate the speedo?

[1987cp]

Pick a cam with enough lift and fairly narrow duration like Crane's 364211 (kind of a flat-tappet version of my cam) and add a Performer 351 manifold (or mooch Nathan_in_MN's factory four-barrel manifold if you REALLY don't care about top end), 500cfm four-barrel carb, and small-tube headers. A set of BHP-ported heads would fatten the torque curve, though they'll shine more with a fatter cam and high-rev governor.

The rear had a lot of miles on it, and there was no rear-end girdle/bearing support. I did a brake-torque launch on hot, sticky R-compound tires. For the first time, the tires hooked hard. The rest was history. The car now sports a 3.27 out of a Town Car.

Our Panthers are heavy. A lot of torque and traction will lead to failed 8.8 bits. Not a bad idea to run a rear end girdle. Cheap insurance.

Okay, I'd forgotten about that story. Sounds like I might want to think about rearend reinforcement. Not that up to 350 lb-ft is really that much .....

Put a set of 69 Windsor heads on, that will give you 10.5:1 compression. My Car has a 69 Windsor and it runs fine on 87 octane gas.

[351wcrayz]

so eh, ANY lists of tried/true parts that arent oober expensive, and will really feel out the lower end of the engine? I know, I have asked various ppl on here, but can anyone help w/ a DEFINANT list of the needed parts, accessories, and machine work needed?

Thanks again for all the info-
