blub blub..blub blub..

I have a Midwest Motorsports solid cam in my 383. Its about this big-
adv dur-287/295
@.050 dur-256/264
lift-545/563
105 LSA
81* overlap
12.85@107mph (traction limited) through 2 1/4" exhaust & 3.23 gears. The 105 LSA made it pain to drive & stage, plus the 6" of vacuum caused all sorts of wierd troubles (carb tuning,pcv & timing).

I just swapped a Comp Extreme solid 274 in it-
@50 dur-236/242
lift-501/510
110 LSA
57* overlap
This cam sucks for my application, but yours may be different. Other people like it, but everyone has a different combo. I dont have any times with it (no tracks open till april) & am changing right now. It does idle like a *****cat and pulls a whopping 12" of vacuum at idle though!

Hydraulic Crane Energizer, 222, .467" lift (using 1.6 rockers, so actually a bit more), 110 LCA. Ran a best 13.7 @101 at local 4,100 ft track. Corrects to about a 13.0 @106 at sea level. Skank 2.17 60 ft. I love the cam. Very mild idle, plenty of vacuum, engine never gets above 170.

My 71 is 3,550 with me in it, th350 w/stock converter, 3.42's, home port smog heads, Edelbrock 2101, 780 Holley, Radial T/A's. Cam makes plenty of torque, which is good cause the heads call it a day at around 5k.

2 Keith Blacks broke , so I'm building another 400, and the same cam is going right back in. Bought it from Summit. 90 bucks w/lifters.

Cool

Here's what I had in my '81 Z28:
  • 383 small-block Chevy, 4-barrel QuadraJet, Weiand "Stealth" intake; "882" casting heads (~76cc chambers), .480/.480 lift hydraulic, flat-tappet cam, flat-top pistons (probably ran ~9.5:1 compression), long-tube headers, true dual exhaust (2 1/4")
  • TH350 3-speed auto. tranny (with a mild shift kit), 3.42 posi rear-end
  • 245/60/R15 Dunlop G/T Qualifier tires
  • Trac-bars
I know that the 882 heads aren't that great, and the cam could have used way more lift, be with that combo the car ran 14.21 @ 97mph breaking down!! (or should I say, leaning out?! ). Yeah, I was pi$$ed! For some reason, when I went to the track, the car (engine) would only rev out to about 4000-4500rpm, then it would start cutting out, and causing the whole car to "buck" (like launching a standard really bad) except this started happening at the top of 1st, and the top of 2nd gear?! I went 2 weeks in a row, and even installed an electric fuel pump and a new filter to try to cure the problem, but it still would not rev to ~6000rpm like it would on the streets around home. I think the elevation was different at the track I went to than around home, so IMO, a 750 Holley would have fed a lot more fuel to the engine, and it probably would have run a mid to low 13 (considering it did cut a 2.0 60' time).

Well, HTH.

My Malibu below used a little Crane Energizer 272 flat tappet hydraulic (272/272*, 216/216* @.050, .454/.454" lift, 112* lobe separation angle). The 13.4 @ 107 run was on street tires in fairly hot weather cutting a medium-sucky 2.2 60 foot time. Stock converter, 2.73 rear gears.

With the blower I never made it to the track (I'm rebuilding the engine for more power right now) but I'm fairly certain it would have run a mid-low 12 still on street tires and with even worse traction problems. And the Energizer 272 isn't a blower cam.

I have had a LOT of good results with the Crane Energizer line of cams in mild street performance engines. As long as the exhaust flows good (good heads, good exhaust system) these single pattern cams make good power. Just as important- they don't beat up the valvetrain. Valve springs last practically forever and there is very little valvetrain noise.

the 406 in my 79 is a Crane hydraulic saturday Night special 302H 06 (Part #270-110111). I run 10.5:1 compression and performer rpm heads. The car runs consistent 12.30s and 40s depending on temp. This is on mt sportsman pros and a stock chassis set up. I know I could get even more out of this setup if I would use bigger heads, but it is consistent, very good on the street, and sounds bad a**.

My 79 383 has a performer RPM 234/244 @.050 and approx .50 lift.

Runs 13.0 @ 105 with a 600 cfm carb.

Cam is about the largest I'd want to use on the street. I had a larger one in the past and replaced it with this one because it was too radical.
