I don't know yet. I'm waiting for him to tell me the specs.

I have a set up for a BB Mopar where the spring for the rev kit seats into a retainer made into the push rod.

You can find out exactly what the cam grind is in the motor, if you want to work
It is harder in the car as you need 360 degree wheel and a good dial indictor with a good mag base holder as well as some stem, extensions but it id doable up

I talked to the engine builder today. He did not have the cam card, because he said he gave to owner. He did say it was 260-280ish duration with the 660/640 lift. Said it was an Erson billet cam with the Morel lifters. and matching Erson springs. Said it a solid set-up that would live on the street with proper maintenance. Said it was actually built to drive on street, with in reason.

I'm guessing that those are .050" durations?
They're very far apart.

I didn't specify right. He said is could be 260/260ish I/E up to 275/280ish I/E @.50

Not 260/280 duration on same cam.

And your communication with him is the reason for this comment above.

You still know as much nothing now as you did before talking to him. If you want a good answer, you need the facts. Bust out the tools.

and that was the engine builder, not the owner of the engine. Would there be a cam # on the cam?

Are you saying neither the person who owns (owned?) the engine or the person who built the engine can tell you the specifics of the cam that's in it? Nobody's got a build sheet or a cam card for it? That's "questionable", at best.

Robinson Racing engines in Ohio built it. That's who I talked to. I am not by any means putting their name to be negative, just stating who built it. He was very curtious, answered any questions he could, and with exception of cam specs (which I know is important), had all the answers I wanted. Looking them up, seemed a mopar knowledgeable shop.

Ok, last question. If I buy this thing and put it in with a tight T/A converter in my heavy car (3.91's), and it is a 270 or 280@50 cam, is it gong to be soggy around town down low? I know there's a trade off to horsepower and puttzing around the street. I know the actual cam card would be an immense help, and I'm still trying to get it.

You need a good converter that is built to match your combo or it will be miserable to drive on the street. With too tight of a converter, you can have idle issues as in needing excessive idle speed to keep it from loading up and trying to die at a light without putting it in neutral all the time. A properly built converter will not have excessive "slip" in normal driving and will be perfectly streetable. When you jump in it, it will flash and get you into your powerband instantly. Lots of downsides to having too low of a stall, no advantages. Ask me how I know! Find out what you cam is and talk to a reputable converter builder about what you are trying to do and I doubt any of them would recommend a "tight" 10", that probably stalls around 2800. If that cam is a 280@50, I suspect a 3800 stall would be on the low side with a heavy car, but I am certainly no expert.

Couple of things. 1) consider starting a new thread with all the info needed. A tight T/A converter doesn't mean much, and we don't know what your goals are for the car. 2) Regarding this thread, just put the right cam in it for your purpose. If we talk much longer about it you could have had it done already. Based on the limited discuss so far, this sounds like a candidate for something like a Comp -5 cam in the 250s on a 112 with Isky 9365 springs, if you keep it under 6500 and lugging around town is the main plan..

There is a world of difference between a cam with 260 to 270 degrees at .050 compared to a cam with 280 to 285 at .050 shock
I ran a Comp Cams custom grind solid roller that had "BB Chevy" lobes on it that was 260 @.050 on the intake lobes with .420 lobe lift and it had a different lobe on the exhaust that was 266 @ .050 with .409 lobe lift ground on a 108 LSA in my old pump gas 400 block 511 C.I. stroker motor. I ended up doing a bunch of parts changing on that motor but I kept the same cam with different lifters and rocker arms, it was really raspy sounding at idle and up to around 2000 RPM in gear devil That rascal was a lot of fun, it pulled really hard from idle to 7800 RPM shruggy devil up
