340 Build Advice

Bought the car in 1987. Stroked it in 2013

480HP @ 5700, 511 Torque @ 4300
488 torque @ 3100, where the dyno started measuring
418 C.I. stroked and poked 340
10.5:1, 92 octane unleaded pump gas.
Crane Camshaft: SR246/362-2S-8IG , .543/.561 L/S: 104 Int. C/L: 108
Full roller, solid lifters, LD340 intake, QF650 DP, Edelbrock heads straight out of the box.
Just a street car... Pulls way harder than the mostly stock 340 did before stroking it.
A833 4-speed, 3.55, 8.75 Sure Grip
Running Mopar HiPo 340 exhaust manifolds too.
A single Plane intake and long tube headers would most likely get it to 500+ @ 6000+ RPM
Just runs out with the dual plane intake and manifolds, which is still fine with me.


17" Year One Rallye wheels, 275/40-17x9 rear, 245/45-17x8 front
Firestone, Firehawk Indy 500 Wide Ova, Ultra High Performance Summer Tires.
They hook really well. Can still fry them at will but really surprised at how well they hook up.
Ride nice too, not too harsh and handle well. Bilstein RCD shocks on all 4 corners.

Have been looking at the Continental Extreme Contact as possible replacements.
Thought about 285/40 but the recommend minimum wheel width is 9.5" and my rear wheels are only 9 inches wide. “¯\_(ツ)_/¯“
