hi i have an 86 firebird and it has the 2.8l v6 and i want to put my 327 and auto tranny into the car, i am having trouble with finding parts and straight answers.

do i need thicker front springs? i hear yes and no(car will be my dd)

ware can i get frame mounts for a v8

will the rearend hold up?(im not going to be nice to it, im 16)

 

Stock front springs are fine. I ran V6 front springs in my BBC car for years. A heavier spring rate will keep the nose up during hard cornering or braking.

You could pull the frame mounts from any junkyard car or just buy a set from the dealer or aftermarket.

Your 10 bolt diff is the same no matter what engine is in the car. The tiny 7.5" ring gear can be broken by a street car and has survived dragstrip use from a big block powered car. I doubt your 327 will cause much harm but that doesn't mean you still can't break the teeth off the ring or pinion.

 

86, welcome to thirdgen.org.

Now, read the "V6 to V8 swap" sticky in the top section of this forum.

 

sweet thanks for the help. i know how to do it all its just the things i have been told may break or need changed and i wanted straght answers insted of "i think".

so thanks agen for your guy's help and i think that dubble hump 327 will be a ball in that car
