If it’s got a stumble it’s probably lean, like mentioned need more info. Only one breather required for a PCV. What’s kind of carb? That’s not a very big cam, although it’s kinda funky. Looks like a thumper type grind (don’t care for those).
You could say it really went off cliff for me. Once I started drilling and tapping I couldn’t stop. I’ve learned to manipulate these things where they run like fuel injection.. maybe better.. lol
Got the same issue on my hemi, but mine is 214grams light on the bob-weight it was balanced at after doing some math. Wish I would have ran the numbers before it was together and in the car… I know better than to trust people..
I get your passion. Once I put a AFR meter in my car it went off the deep end. My passion lies more with Holley type carbs and dominators. I’ve built and tuned numerous carbs on my 512 roadrunner. It’s been a hell of a tool! With everything I shoot for drivability as well as WOT performance...
Got my Hemi going. I have a pair of L88 vacuum 850’s on it. List 3418. It was stupid fat with the factory calibration. Right around 12’0-11.9 at idle. Idle screws were un-responsive. Went into the 10’s with some throttle and was just loading up. Made my first whack at it, dropped the IFR from...
The hyd rollers are very temperamental to the oil viscosity. Wouldn’t run anything heavier than driven 10w-40. It’s the centistoke rating of the oil that messes with them. I just built a big block Chevy with a hyd roller for a buddy. I kept the clearances a little tighter in the bottom end than...
Pretty stout cam for a driver with 3.55’s and a 5 speed. I’d get away from that 108. Probably something on a 110 230’s/240’s duration with as much lift as possible for the lobe family (general of course). You leaning towards solid or hyd? Those new comp hyd roller lifters with the replaceable...
Thought i would share, I recently had to steal the smith 26” alum radiator out of my roadrunner as it was set up for my Dart (which I’m finally putting back together after several years). I bought a 26” Griffin for 70 model mopar. 2 row of 1.25” tubes. I bought a brand new shroud for a 70 26”...
That’s a solid flat tappet. My buddy ran the same cam in his 472 (Barton built). His was around 12.1, ran super strong. Ran 10.40’s through tail pipes in a full weight 68 B body. He drove the piss out of that engine on the street for years.
I’ve talked with Ray a few times. Great guy! He’s all over on these intakes though. He told me a ported single plane and ported xram would make the same HP but the xram would make more midrange torque. He also told me his xram and the mp xram would make the same power. A friend of mine had his...
