Dammit summit.......Dammit

Hi Mudrat, I am not going to shoot the messenger. I talked to my engine builder and he said during the rebuild every thing worked as it should, he also said that a lot depends on how the cam is broken in.After all, he has to guarantee the engine! The guy whom rebuilt my engine does racing engines. (Speery Engines Cedar Rapids,Ia)

Roger that.

HEY!!! MC... did you figure out what happened?
Curious minds want to know

Mc, I finally got a reply from Summit on my SUM 8600. I thought this guy was going to go postal with his reply! He told me to beware of chat forums, Geeeeez I thought I we were talking about Jeeps not just a chat room.
Summit definitely does not want to have any blame placed with thier cams. He also said AMC people do not want to change from bridge pivot rocker arms to the adjustable which is required according to Summit this list goes on and on so think I will get off of my soap box. The more I read his E mail the more Po'd I get.
I trust your opinions and the work you have done for me now and in the future. =D>

Summit wants to cover their butt cant hardly blame them for that....HOWEVER telling us that it isnt the camshaft when it is and also not standing by their product will and has turned off alot of their customers. These "chat rooms" are where people of unbiased opinion can discuss their experiences. Summit is aware of Bulltear and so is comp cams and they both have members here. These companies do have great products but even with a small percentage of scrap that makes it out somebody will post their experience and we should not be silenced for having spoken our minds.....

FWIW I believe both of the cams are about equal in quality

I think It's called the first amendment...????

I'm running an edelbrock in my 304 and I can't complain a bit about the cam.

[jeepsr4ever]

haha yeah that cam is definately a good choice for a 304 It was designed for use in a 304

Can we re-address one of the earlier questions? What's a good substitute for the 8601? I'm about to build a 360 for my Scrambler and thought that was the right choice.

[MC]

Tell me about your drivetrain John.

[John N]

It's a Jeep Scrambler, has a weak remanned 360 in it now (low miles), Howell FI on an Edlebrock Performer, DUI ignition, stock dog leg exhaust manifolds into a Y pipe single exhaust. Running a TF999 automatic, Dana 300 transfer case (new one on the bench going in soon with 4:1 gears, clocked, twin sticked), Dana 44 axles front and rear with 4.09 gears (ARB lockers). Tires are BFG M/T 33's, might go to 35's eventually.

The engine I'm about to rebuild is a (supposedly) '72 360. The head #'s are 3212993-1 with the individual rockers (are these studs pressed in or screwed?). The bores are in decent shape, but haven't been checked out completely. I can't find anyone with specific AMC knowledge in my area to build it, so I have to, pretty much, specify what I want....I'm looking for low end grunt off idle for off-road and decent street performance up to 5000 (okay I'll take up to 4500 rpm). I figure 300 hp should be possible on regular gas. Am I asking too much? All my friends are Chevy and I don't want to......
Thanks....
