I need to Identify this

ok i bought this 72 fleetside from a guy, he dont know what the motor size is. he says its a 86 crate motor. the #'s on the block say its a 350 as to chevy e-mail page. but guys I needed to buy a starter for it one time in the dead of winter, the 350 didnt mount because of hole pattern. is there a way to exactly know without tearing down the motor and checking cylinder bore size??. this sounds real bad but I cant identify what I have,, any help please

There are two different small block chevy starters that I know of. One has the two holes lined up, the other has them on an angle. You probably have the wrong one. A small block is a small block pretty much. Look whats on the block, straight holes or angled holes.

Get your casting # and got to www.mortec.com maybe that will help!

tphsmith · 12-25-2003, 12:33 PM

ok I see that. and I understand. but ya know how ya got something and it just drives ya crazy till you know exactly what you have. the guy I bought the truck from said he thought maybe the motor was a 305, but he realy couldnt rem. sheesh this is driving me crazy. the bolts on my starter are angled. it just drives me nuts maybe I have a 350???? maybe I have a 305, sheesh what is it???? help

2 years ago I sent them numbers to mortech, they said they would look into it because at the time they haddent seen them numbers, I told them it has stamped in the block made in mexico in it and I wanted to know what the real year was on the block, well they never replied and now on their page they show the numbers I asked about, but they show no year on the numbers, makes me suspicious that I sent them the numbers and they added the numbers to thier list and went with that.. NO I dont know but I have looked and e-mailed Mortech about this. I just still dont know what this block is.. is there a way to tell without ripping the darn thing down to find out is it a 350 or a 305??

tphsmith · 12-25-2003, 12:47 PM

someone told me the heads on a 86 would have center bolts in the valve covers is this so???

**lolife99** · 12-25-2003, 01:10 PM

No. Center bolt heads started in '87.

tphsmith · 12-25-2003, 01:13 PM

fhew,,, thank you , I realy have never seen center bolts in a 86 but I wanted some one else to say it also

jhow66 · 12-25-2003, 01:27 PM

Does not matter as to engine size(262-267-305-307-327-350-400) as there are only 2 starters-one fits small flywheel -153 tooth-one fits large flywheel-168 tooth. You have angled bolt pattern so swap for straight bolt pattern.

OLDCHEV4X4 · 12-25-2003, 05:10 PM

If its a stick it might have 3 bolt holes.

jhow66 · 12-25-2003, 06:46 PM

Most all blocks have the 3 bolt holes. You can use either starter on all blocks. The flexplate or flywheel dictates which one.

ckhd · 12-26-2003, 10:06 AM

The three holes he was talking about was for the manual transmission starter. for 67-72 then the starter bolts to the bellhousing for MT instead of the block. Bolts to the block on AT.

Is it a MT '72? If so, don't mention a thing about the engine being an '86, just tell them '72 pickup, 350 and a MT. They will get it right.
