i have a 87 firebird with a 2.8 i just got a 88 astro van with a 4.3?

Question

can i take the 4.3 and put it in my firebrid im sure i can but where can i get the moter mounts for the swap

Answer 1

you guys need to read his question again

he wants to put the 4.3L in place of the 2.8L

he just needs the asto van mounts and brackets, thats all

very simple

he already has what he needs

he will have ot deal with exhaust issues though and have to swap the tranny too

he will have to get the B&M tranny swap brackets in order to bolt the van tranny into the car, because the tailshaft housing on the van tranny will not allow the torque arm under the bird to bolt up to it

82-up firebirds and camaros

70 dollar kit

summit carries the brackets,

the van should be a 700r4,

he will already have the right driveshaft if its an 84-up car, or a 5 speed one, the shorter driveshaft they used under these cars,

length is the issue

82 and 83 f body auto tranny were 3" shorter and was a longer driveshaft

the tranny behind the 2.8 wont bolt to the 4.3 engine, the 2.8 is 60 degree bellhouisng pattern and the 4.3 is 90


happy swapping

Answer 2

Yes it can be done. A 4.3 is basically a small block chevy without two cylinders. Also easy to put a 350 in that astro van using most of the 4.3 mounts and accessories. You may want to double check by measuring from the back of the engine block to the engine mount bolts on that 4.3 and find a chevy V-8 and measure it as well. The mounts for the V-8 for that car should bolt everything right into place. You will however need a different transmission, as the 2.8 is what they call a 60 degree V-6, meaning the angle of the cylinders is only 60 degrees where 4.3 and small block chevys are 90 degree V-6 and V-8. A lot of parts interchange between the 4.3 and 305's and 350's. So you will need a transmission with the right bell housing for the 4.3 in the Firebird. Other than that, everything should bolt right up. The hardest part should only be figuring out your wiring. You'll probably need the computer and the engine bay harness from the van.

Answer 3

i own a repair shop,and the mounts are going to be the same ones that the small block Chevy would use ,so when you hunt mounts ,,just look for some for a camaro with a v-8,,i have did this before,,the 4.3 is a good engine,and runs good in a camaro,,good luck with it,i hope this help,s.,,have a good x-mas.

Answer 4

Best bet is buy a crate motor. I droped a 350 into my 87 trans-am. Talk about a sweet ride!

Answer 5

if they don't make the motor mounts you can make your own out of half inch steel plate like they do for mopar conversions such as a 440 in a duster.

Answer 6

if your going to all that work, go ahead and put in a 5.7 :)
