Do you still have the Challenger ducktail wing for sale? What brand is it? How old? THANKS!

I think the strength of the 9" has to do with the 3rd pinion bearing on the nose of the pinion, supporting the pinion from both sides with 3 bearings. The 8" has the same deal also. I have not broken any of those rearends, but I have seen a 9" years ago with the punkin case cracked at the...

If I break the 8 3/4, I will upgrade then. As an interesting side note about the 8 3/4, years ago I ran a Super Comp dragster, 427 brodix headed, [email protected] solid roller Chebbie, glide, 5500 stall with trans brake and 4.10 gears with a 1 3/4" pinion. It ran 8.40s @ 167, but I wanted a better 60...

I have: 3 billet main cap kit 5 billet main caps kit 5 billet main caps with cross bolted center 3 cap kit. Has anyone done the crossbolted caps? How about experience with reliable street HP levels of the different caps and stock caps with ARP studs, which I will use with any caps I go with. My...

Header tube diameter, tube length, collector diameter, and collector length will all affect torque and horsepower production. Larger diameters will "rock" the torque curve around point of peak torque favoring HP and diminishing torque, while smaller diameters and longer lengths favor torque...

Was the 1 7/8" a misprint? 1 5/8" on a street small block works great, but 1 7/8" drops the bottom end torque.

1 7/8" headers are race only deal. They will kill all the torque below 4500 rpm. Bad choice for your dual plane intake and small FT cam. You really want about 260 @ .050 and a Victor Jr. Intake with those headers. A better street combo would be 1 5/8 headers, dual 3" exhaust with crossover at...

I'm in Avondale,AZ. if you need any local engine/drivetrain expertise. I'm doing a 72 Challenger with a 512 transplant. Mine was a 318 car, then mild 360, then a stroker/ roller cam 390" motor with a lo gearset 904, next a 440 ported and cammed 727 trans currently until the TFS headed, solid...

My 72 p/s, p/b,a/c big block Chevelle had underdrive crank pulleys, and both the a/c and p/s worked fine. It did have 3.73 gears and a 3000 stall though. No issues at idle in a parking lot at all. TIMINATOR

Well then how do I figure out what if any damage has been done to my Duster with the 4.30 gears and 3000 stall convertor in the last 26 years of driving it here in Phoenix,AZ. where it gets to 115 degrees every summer? What should I check? The fluid smells fine... I Would think that a cooler...

Why a P/S pump cooler anyway? Trying to go resto, or do mopars need them? Only one ford I had used one and no GMs that I have had so far. Are they needed for mopars? TIMINATOR

Most folks like the sublime, but the Panther Pink is a love it or hate it deal! In between mopars I had a Panther Pink hi 9 sec. Street 72 chevelle and a blown 68 Panther Pink lo 9 sec. Street nova. My body shop guy said buy a mopar! My plans are hi 9s in street trim on the motor and squeeze it...

WOW! Thanks guys! TIMINATOR

OK. Saginaw pump it is. Where do I find a pulley for it? Are they all the same or are there different off sets? When I buy hoses are they the same for both pumps or do I specify which pump I have? Thanks! TIMINATOR

Post got chopped. Federal or Saginaw pump?

I recently bought a 318 p/s and p/b 1972 Challenger less motor and am building a 440 stroker for it. Since several sources list both pumps and brackets for sale, which would be the better choice to purchase, and why? They both are close in price, but is one easier to get and although both are...

Boy did I spend a BUNCH on their last Black Friday Sale! Aluminum heads for both my big and small block motors, billet stroker crank and rods for the 512, along with the big single plane intake, billet main caps, offset roller rockers for the RB, aluminum water pump and housing, water neck...

The 1615 duplicolor seals the pores and makes the manifold easy to clean. Mine has been on the car for a few years now and still looks good. It's also gasoline and Autozone brake cleaner resistant too. But the O'Reilly brand brakecleaner will remove it or stain it. The O Reilly brake cleaner...

What's the hole in the bottom of the exhaust crossover for?

No arguing, but I ran the Chevelle for 3 years with a Hughes 3000 convertor and weighed 3650 with me in it. It stalled 3800 on the foot brake (one of my part time guys worked at an industrial brake and clutch place and put soft linings on the entire length of both shoes). The bored 454 (482")...
