    300 HP out of a 318, is it possible with bolt ons?

    Bolt-on's I don't know. Starting clean-sheet but on a budget, get '85-2002 replacement pistons (more compression height than the older pistons, even the 4-eyebrow early style) and start with #302 casting (heart shaped chambers) heads, modified for 360 valves (1.88x1.60"), with chambers...

    Camshaft id please...

    The MoPar PurpleShaft solids are .028/.032" pretty much across the board, I always set mine at .024/.026" HOT and had no problems. Much less noise, and I ran them with 1.6 rockers as well. Play around with it, but unless you are lacking bottom end, tighter will be better up to a point.

    How strong is an a-body 8.25 and can you make it stronger?

    Yes I used it to replace a 7.25" in my '71 Demon (318 car), and it held up to hundreds of runs with a 400hp 360 (mid/low 12s) and a 525hp 416 (low 11s) but I was footbraking with 3.91 gears and a Sure Grip. I haven't inspected it but it worked fine when I ladder bar'ed the car with an 8.75" and...

    [WANTED] P2843177 MP solid lifters, partial set 4+

    Hey everyone: Looking for an incomplete set of P2843177 solid lifters (hollow, with the pushrod seat held in by a snap ring). Maybe you broke a set for a Slant Six and have the 4 spares, or maybe just extras laying around. I need these to complete a partial set I have for a V8 application. Thanks!

    Oh dear God! 318 stroker

    My first 4" stroker was a SCAT cast unit (stronger than Eagle, but this was in '99 so nobody really knew then) I got from MoPar Perf. It had to have Mallory metal with lightweight SIR Eagle rods and Diamond dished pistons, which I thought was odd. The last one I did, I used Magnum 5.9L external...

    Oh dear God! 318 stroker

    I don't own the Barracuda, it's "Gary's Garage" on YouTube. I am, however, building a 318 Magnum based 390 (dished pistons, RHS heads) for my '99 Dakota R/T ext.cab. It's a heavy truck and I want more bottom end but really don't need a 408, so I used an old 5.2 block from a '92 D-150 shorty that...

    Oh dear God! 318 stroker

    I'm thinking the pin overlap might be adding to the Eagle crank failures. A good many of the failures are from people with engines far beyond any cast crank usage, like really high RPM or boosted applications (nitrous/etc.). Your lightweight skinny rods will help and the low RPM ceiling. When...

    Oh dear God! 318 stroker

    These guys^ did exactly what you are describing, and 20+yrs ago, "Speed-O-Motive" offered a kit to make a "350" MoPar 318. The guys in the video had to relieve the bottom of the pistons near the pin bosses to clear the counterweights, but they used replacement pistons for a super-low compression...
