Hi everyone, I was wondering if anyone could tell me about the a237 rollor cam. How streetable is this cam? I'm still running the stock cam in my 85 TC w/the stock T3 garret (.60/.48 a/r) set too 18 psi, AFPR set to 42 psi, intank 255 lph pump, and a FM intercooler, Ported E6 manifold, and mildly ported intake, and a 3" DP and dual 2.5" exhaust w/dynomax race bullits, I'm still running the C3 auto, but i am swapping in a T5, the car also has a '87 TC 8.8 raer w/3.55 gears, It also has a Big VAM unit and a K&N filter up front.

I'm also going to swap in a T3 garret (.60/.63 a/r) i got from a friend when i swap in the T% tranny.

If anyone could give me any info on the a237 cam or a different cam for my car i'd be greatful, I want to make lots of power, but i need to keep the car somewhat daily driven and streetable. Thanks

It idles a little rough, you will lose 2-3 " of vacuum. It's streetable but doesn't come alive til about 3K, then it pulls all the way to red line, hard. Seems to work best with 4* advance on the cam

I have run them in a few different motors (I have 3 of them)

I like them. Passes emissions with no problems. Good drivability in low RPM's. Like Pete said, the do have a lumpy idle.

I run mine at 2 degrees advanced. I had run at -2,-4 and it was way too high in the rpm's before the power came on. When it did if felt like the car was going to rip apart.
I ran straight up at first, then after tring retarded went back to 0. Then Barry Dean recommended +2 to +4 to me. I tried +2 and it has stayed. Brought my power band down about 500 RPM and I lost very little on the top if any at all. Comes n smoother now.

I have never run one in a stock valve head though. I was planning on tring soon, but have not done it yet. Even then it will be ported up pretty good.

All were run with T3's.

I have been trying to find a vendor- but am having either a lapse or brain fart- and all my attempts at "searching" are returning fruitlessly.

Does anyone know a couple reputable dealers?

I'd like to look into this further.

Tiny Avenger used to have them (A237) but I think I heard they may not have any more.
Somewhere, somebody posted which Company made these for Ford (I think) but I can't remember which company, maybe Crane.

i can, but it's cheaper to use a set of ranger roller followers. i double check the price.
