Dammit summit.......Dammit

[rollen dean montoya]

i generaly use crane cams but did use a trw cam on a buick 455 i installed
in a 67 firebird and had no problems. used crane cams in my other rebuilds(71 eldorado 500 v-8, 77 formula firebird 403 olds v-8, and a
friends 87 buick gnx 231 v-6 turbo). with shoddy quality control summit
needs to be stricken off the list on where to get parts!

I have heard that Reed Cams are really good for AMC applications. I have not tried one personally, but a lot of AMC race guys like them.

Just my two-cent's worth.

I have run nothing but comp cams and have been very happy with them . I have no complaints about the product at all!

i done got the 8600 cam, its installed and just started the motor last night , runs good so far. purchased the cam begining of june. when did these bad ones start to pop up? followed jeeps forever suggestion, was going to go with the edelbrock. is there any thing i can check in preventive measures?

[rollen dean montoya]

1st look at the finish on the lobes. if ANY are unfinished(ruff) then
return and go with another bumpstick from comp, reed, crane or any other reputable company. just my opinion.

Well I found the problem

the relief holes in the back of the cam were blocked by flashing and one summit cam we have here has no relief holes.................dangit, do I have to go through everything

[rollen dean montoya]

you might have to. i look at the bumpsticks before i walk out of the parts house. picked up a trw for the 67 firebirds 455 and it had a flaw. the #4
cam lobe was not polished correctly and trw happily shipped a new one to the house no charge. it also came with a hand written apolagy from the
inspector who missed it. but that was in the 70's.

was it a 8600 or 8601?

Hey MC
I purchased a Summit 8600 cam this year on your recomendation for my 304 which is now rebuilt and ready to go. Are these cams any good or not?

I can't say, but I can say 'don't shoot the messenger'. Summit has been a Name for years and (usually) has good stuff. I've gotten stuff from them for years with no problem. But I don't think they make their own cams, but contract out to their their specs. My guess from this thread is that they don't QA 100% of their products.

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)
