Slightly disappointed in performance
Just stick a 292 mopar purple cam in and make some power!:D Let the bashing begin!!:lol: Oh the 108° lobe separation version.
That's what I did. With 3.55s. I thought with a clutch I could get away with it. I was wrong. That cam even at 11.3Scr didn't even wake up until over 3000 rpm... which with 3.55s and a 2.66 low gear, comes at 25mph. So wrong gears for the cam, or wrong cam for the gears. I got rid of it. Not for the above reason alone mind you, but because with a clutch, the engine is married to the rear tires, and slipping it out like a grain-truck was was not very Mopar-like.
The minimum driving speed was about 750 rpm so 6.25 mph, making parades and car-shows impossible. Yeah I advanced it, but at 11.3Scr,she already had a ton of torque, just not at 750 rpm..., So yeah, I advanced it some more, with predictable results.So I retarded it to straight-up, installed a A833od, and 4.88s Oh Yeah.
And I'll tell ya, she was a ripper after 5000, all the way to 6500 and I usually shifted her at ~7000; but 65mph was 6800 in second; now yur talking.
Well sorta. First gear at 3.09x4.88=15.08 starter gear was ignorant. But the silver lining was 750=3.9mph; walking speed, horrah. The bad was 30mph was 5750 in first 3100 in second, and you can see how ugly that was.
I think I pulled it out in late summer. I don't miss it.
After that is when I installed the Hughes 270/276/110 (223/
[email protected]).. That's 3 cam sizes,if yur counting. And IMO was just right. I loved this cam. Out with the 4.88s and in with 4.30s, and got a GVod and started splitting gears; badaBoom. 3.09-2.41-1.67-1.30-1.00-.78-.54 hyup 7 nicely spaced gears. A couple of gear changes later And she was wearing 3.23s, and then back to 3.55s.
For a streeter it's all about having the right amount of torque at the right time. If you got that, then you don't need absolute power, cuz you can only use it once at the top of first, and usually the tires are spinning anyway. If you have a TF, the 1-2 shift is where things get cranky, cuz the split is 59%. If you short shift into second, well your engine better have some juice down there. Most guys don't build to spin very much past 6000, so if you shift there, then 59% is 3540...... way below peak torque of a 292 cam, so she's gonna struggle to maybe 3800/4000 to find some pull, and with 3.55s that will put you right around 65mph.So you hit the speed limit right when the cam is waking up the second time. Bad news you lose, to the guy who's been on the powerpeak already for 200/300 rpm, even tho he might have way less power, Ima thinking a cam up to about 3 sizes smaller.
That 292/108 had a great top-end rush, and woulda made a great race-combo with the right gears. For me, the 292 was just all wrong.
