some guy told me today that if i was doing an engine swap that i should put an S-10 4.3 v6 block in to my camaro today...he claims that block to be a 60 degree block but its a truck engine and from what i understand its a pain in the @$$ to make a truck engine fit. is there in truth in this guys opinion or should i stay with a 3.8 swap?

 

The 4.3 is a 90* block (same as the 3.8). It is just as hard to swap a 4.3 or a 3.8 into a V6 thirdgen as the transmission will need to be replaced in both instances.

The easiest swap is to change the 2.8 out for a 3.4 found in the 93-95 Camaros and Firebirds

 

even if you had a trans for a v8 a 4.3 would require differant motor mount locations and a few other modifications to make fit
