Let me just ask here. What exactly are you buying and from whom are you buying it from?
A 235 rebuilt engine from a local engine shop
Shop built engine and customer never came back
At first I was under the impression the engine was complete
Just missing manifolds fly wheel and bell house
Turns out it’s just a block and head built with new stuff
No timing cover
No dampener
No side cover
No valve cover
No oil pan
Etc etc etc
If engine was more complete as I thought I could do the swap
Quickly but with all the missing parts it’s more of a parts hunt and no longer a quick swap.
