ZOWZIERS! I thought you were gonna say small block and twin turbos. No replacement for displacement!
NICE! something that could be built in anyones backyard.
It was too. I built that before I had a metal building put up at the old house in Macon. It was on an engine stand just outside the fence under a blue tarp. lol
What Crane # is this “ Magic Cam” you speaketh of??
Hyd flat .467/.494 222/234 @ .050 on a 114.
68 Dart with a 440 - 727 trans and 3:23 gear. 11.40s in the 1/4.
care to share any details on the engine? I ask because I'm going to be starting on my 440 in the near future...
73 Swinger 5.7 Hemi 88mm turbo 3.23 gears 8.93 @149.9 mph 1.21 60'
Mopar 590 solid cam, Edelbrock heads, Edlebrock dual plane intake, Edelbrock 800cfm carb, TRW 10.2-1 pistons.
I've managed to run 12.63 @ 107 with 7 & 1/2 cylinders and a fuel supply issue with Crower's version of this cam. I also have 3.73 gears. Mopar Hydraulic Flat Tappet Camshaft - Camshafts
That looks like a great cam for my 360.... seriously considering
Considering that I also ran a 600 Eddie and a lowly Performer manifold not the RPM and only 9.6 -1 comp it certainly should go quicker in its next incarnation. Oh and I almost forgot.....ported 318 heads
I went 16.7 at Bandimere with my Barracuda back in the early 90's with 3.23's and a fairly stock 318....MAN that thing was slow, but I thought it was fast back then, lol!
12.41, 71 Demon mild 340, 727 9 1/2" dynamic converter (4500 stall) 275/50R15 Mickey Thomson ET Streets 8 3/4 3:23.
I had some video of my Challenger but it's on VHS! I remember watching the videos and my buddy and I both agreed that it was pulling at least the left front wheel off the ground....JUST a smiggen. Was hard to tell though.
how is street driving with that convertor?
Great, would never know just tooling around town, very happy with it.
I accidently left in second gear many years ago. 1.45 2nd x 4.10 rear equals 5.9 slr. A 2.45 first x 3.23 is 8 slr, much better! 33 inch x15 slicks, 535 stroker, 5000 stall. I had dialed 10.40 but fell off to 10.60 et. 3400 lb race weight. So you can see torque and high stall speed really help. IMHO a great combo would be 2.74 low, 3.23 rear, biggest shortblock you can afford, and a high stall lockup converter of at least 3200 rpm
the Mopar Performance News magazine did an article about that exact problem. their thought was to make the engine work harder but use less rpm. kinda like the 53 Studebaker with a 500 inch Caddy engine. I don't believe it rev'd over 5500 but was consistent 11's...at least that's what I remember.
what lifters are you running with this cam? Also, what converter?
70 Dart, all stock body, full interior, 8.5 comp 360, bored .040, crappy smogger heads,cam was .444/.467, stock Chrysler electronic ignition, Edelbrock air gap intake and 750 Performer carb, TTi headers and full 3 inch exhaust through to the bumper, stock 727 w/stock convertor, subframe connectors welded in, adjustable pinion snubber, 8.75 with 3.23 gears and a Truetrac diff, 245/60 R15 BFG drag radials, weighed around 3750 with me in the seat, ran consistent 13.80s with a best of 13.78 ~ 100 mph, shifting at 5500 rpm. If I ran it on the street tires, Cooper Cobra 235/60 R14s, it would go 14.0
Just generic hydraulic lifters cant remember where they are from. Converter is currently a Turbo Action 3800 and I had a cheaper locally made 3200 stall in it earlier and they both stall around 3200. With that said my 60ft is 1.853 and your is 1.863 so with your crane cam your building good cylinder pressure and making good torque at the start.
I'm thinking of ordering that cam for my 360 (I already have it in my summit cart..LOL). My SM heads are begging for more cam. I'm going to up my gears (2.94's are nice on the highway, though) a little, and shed the stock converter for a better one.
What comp will you be running? That cam cruises nicely at 2000 rpm doing about 30-40 mpr with a small TQ and pulls about 14 inches of vacuum at idle.
I'm leaving the engine alone, I'll just be swapping cams in the car. Goal is to just bump up the cam, converter, and gears some (not a lot) to keep the street manners in tact but get the ET down a bit and MPH up.
