THANKS YOU poncho62 for the info i needed,So my next question is,is this a good block? I guess it being a 4 bolt a good thing

[poncho62]

It doesnt say its a 4 bolt main block...it says 4 barrel carb........

It may be a 4 bolt block, you would have to pull the pan to check that out. A 72 block is probably a good block. It wont have hardened valve seats for unleaded fuel. You might want to find some later heads or even Vortec heads....

Being a 2o or 30 series truck block chances are good it is a 4 bolt main block ,if you pull pan check for wide parting seam on crank throws ,wide seam =steel crank ,narrow seam = cast crank..

See what I mean???

The 010 block was never used w/a factory roller cam. It may be a 2- or 4-bolt bottom end, 4-bolts are commonly found in trucks/vans/buses as well as some high performance passenger car applications.

See ID Chevy engines for more info.

Why do you care what the block cam in originally? Everything you NEED to know is above- including links to databases to look up the suffix code.

Not trying to bust your balls here, but camming an engine for the sound it makes when idling is not the most intelligent way to go about things.

You can do a search on how to choose a cam for more info on the subject. A page w/a little info: http://www.crankshaftcoalition.com/w...ose_a_camshaft
