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...

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.

The Norris is: #356DMS 304/312* 244/258* .534/.517" 107LSA .030/.032" LASH

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...

Just got the PM, I was on the road all day yesterday coming back from the No Name Nationals in Missouri.

Interested. PM sent.

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!

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...

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...

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...

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...

I need the steering center link, sent you a PM, thanks! RB

Six hundred dollars?? Wow

Anyone?

Go ahead and use RED Loctite, the myths about disassembly are exaggerated. Looks fantastic!!!

Those who recommended the 340 cam are leaving a lot of torque out, but it would idle decent and have a broad band. From personal experience with street trucks and tow rigs, a 110*LSA would put you in the torque band quicker and with a higher peak. In my '86 D250 tow rig, I used the 272H-10...

Magnum engines made a believer out of me in the early 2000s. I was a big block guy until 1999 when I built a '71 Demon with a 360LA. Had a bunch of fun with it, and I had a '68 Dart with a tired (but quick!) 400 BB and 4.30 gears. I cannibalized the Dart for parts and put a mildly modded 1994...

Looking for a V8 (273) center link, putting a 360 in a '66 Valiant. Thanks in advance.

I would NOT recommend an 8.25" rear for 4spd drag or transbrake automatic cars due to shock loading and the crush sleeve and c-clip axles (27spl.) primarily.

The 8.25 has it's limitations for sure, but I believe it's closer in strength to say, a Chevy 12-bolt, than people think. It's not an 8.8 Ford, or even a 9.25" Chrysler by a longshot, but I have used several, especially one, beyond expectations with success. My '71 Demon started out as a...

The OG Street Hemi B/RB cam had 284* duration and .471/.474" lift (split pattern) and 108*LSA. Mopar Performance reeingneered the Direct Connection original to: 280* duration with .474" lift (single pattern) with a 110*LSA in the late '80s if I remember correctly. Comp Cams' Magnum and Isky Mega...

.921" on some early Olds, like SOME 425s in Toronados and short-stroke 400s (442 early).

They say on their site that it requires the special lifters with a 1.00" foot. When I ordered my custom Mini Express (?) from Kevin Cantrell, he reiterated that to me, as did Jerry. Mine is on a 106LSA.

LOL, the Mini-Express was always a BB wedge cam and the Magna Velocity was SB, for long oval track use I believe.

I talked to Jerry and Kevin about it, the Mini-Express was never a SB cam, so IDK what they started with, but it maps-out to the same lobe as the BB "M-E" cam. The BBs were ground on a 107LSA and I had them grind me one on a 106LSA. The Magna-Velocity is on a 110LSA, and has more duration, so I...

I too assumed the MP rods were just dolled-up originals, but NO, they are new forgings of better material (4340 I believe, possibly 5140) and bear the word "Mopar" on the beam as well as their "P" prefix part number. Same with the BB MP rods, they had a standard and "6-Pk." rod available at the...
