are these blocks the same or are there differences?
reason i ask is i have a l98 block from a 91 camaro i was going to build for my 85 k5. i found an assembled vortec block really cheap. but it has no timing chain cover, oil pan, ect.. its just the shortblock. i have all that on my 91 block
and was wondering if the 2 were the same befor i bought it. its cheaper then buying a rotating assebly for the 91 , or all the missing parts for the vortec block if all the parts interchange.
both are 1 pc rear main blocks, and hydrolic roller blocks.

thx for your help

 

For all practical purposes, the same.

Where in Memphis?

 

im in the suburbs of memphis actually in germantown.

thx for the quick responce btw!

so basically everything is interchangable?

 

something o forgot to ask...

is the flywheel bolt pattern different?
i know the vortec motor had a 4l60e behind it, where my other block was a 700r4
i know with like the ls1 motors you have to change some parts for a 700r4 to work behind one. any weird issues like that with one of the vortec blocks?

 

Yeah I lived there for a while but never that far east. I did work in C'ville for a couple of years though.

Bolt pattern on everything is the same.

 

collierville is right down the road, im at hacks n winchester

thx sofakingdom
