What can you tell me about about this set-up? These are the specs for a motor built by a local machine shop. Any ideas on its potential? Anything you can tell me about it or any comments about it would be much appreciated. Thanks.

That's a horrible cam. It's the generic grind that's available from Elgin (which is the source they quoted), Sealed Power, Melling, etc. etc. etc.; as well as from Edelbrock, as the "Performer RPM" cam. It's an old design, lazy ramp, typical "too much cam" cam, that doesn't give near the performance that a modern cam with the same driveability. Look at the Comp XE268, or the Crane Energizer of about the same size (they call theirs a 270 something, 272 or 276 or whatever), or one of the modern more agressive Lunati grinds (specifically the "UD" ones, since Harold wnet to work over there) of about that size, etc.

It's impossible to guess what it will run like without knowing what the heads are. That would depend on what casting # they are, and what work has been done to them. Although, with .100" of angle milling and a 66cc chamber, it sounds like 882s (yuck). I didn't know you could even angle mill those that far and still get a head gasket to seal. If that's what they are, I'd pass. They suck.

The short block looks OK for a street motor. Just typical generic street parts.

What kind of $$$ are they asking for it? Can you have them build one to order, and change the parts that are lacking? If so, maybe you can do some business; if not, I'd keep looking.

 

that would be the biggest hint to me not to get it.

 

i just figured it was a typo. i ithnk what he meant to say was chevy 350 +.060

 

Thanks for the help, comments, suggestions, and opinions given already.

The 360 was a typo. Oops. My fault. LoL

I probably should of included all of this in my initial post. sorry. I was suspicious of the heads myself but didn't know. That is actually one of the reasons for me posting this is see what others thought.

I don't know a whole lot about engines but I do know that w/ SBCs the common combustion chamber sizes are 64cc and 76cc. I personally haven't ever heard of stock heads w/ 66cc combustion chambers. That doesn't mean that there isn't a set out there or that there couldn't be stock heads that have been machined (if that is even possible and if so why?). Knowing this I didn't write them off immediately.

I also did a search on Google to see what I could find and I came up w/ nothing. The only 66cc heads I could locate through Google were aluminum SBC heads (these aren't) and Ford heads (yet another no-go). While I was at it I also did a search on the casting number: 487. The # 487 turned up to be 76cc heads. The valve sizes fit with the casting number along with the pictures of the cast marks on the 487. The only thing that doesn't match up is the combustion chamber size. So I'm thinking the 66cc was a typo on the specs sheet and that it was supposed to be 76cc instead...?

Anyways, to answer some of the questions and to help you guys out a little more. The motor was purchased for $1,200 as streetable motor that runs on 93 pump gas. The info that in the 1st post was taken off of the spec sheet that came with the motor. The casting # for the heads are 487. The intake is an aluminum Pro Lightning Power Plus (I have heard this is a knock off of Edelbrocks intake.) It is topped off with a 760 Holley Street Avenger.

With the 487 heads and the cam that is currently in it how do you think this setup would run? What about with one of the cams mentioned above. Any idea on the mannerisms the cam that is currently in it posses?

Not expecting anything spectacular out of it I'm just curious as to what I have on my hands here. Thanks again.

 

a 350 bored .060 over either means it's been rebuilt twice .030 over, or once .060 over. both of those are bad signs to why the engine had to be rebuilt twice, or why they had to bore it out .060 over when they rebuilt it. i personally wouldn't get it.

 

I mentioned this in another post about the $799 engine specials that they have at Autozone, or schucks. Anyway I have seen some that have been tore out after a year, and has been bored .80 over. Motors that cheap, you get what you pay for.

 

Sounds like a very stock short block that has been spec'd to death. I'd expect 225-250 horse. Enough to let you know its a 350, but not enough to win street races.


As far as autozoo motors, and other cheapo re-builds, its not uncommon to tear one apart and find ONE bore .060, and the rest standard. I tore one down that was .060 in 2 holes, standard in the rest, with the original bearings... meaning they re-used them since they were still "good"
