swapping 1987 305 to older 70's 350 HELP, need info????
Hello everyone i am new to engine swapping and know little about what stay and what goes??? lol but anyway heres my dillema.
I have a 1987 Camaro Z28 with a stock 305 and T5 Transmission in it which recently i've pulled out (the engine not tranny) and am planning on installing a GM 350 block,# 14016379, which came out of a 77-79 GM Passenger car i believe from looking up the engine codes.
now my friend says all i need is a different flywheel to bolt it up to my T5 trans is that all i need?? if so, what flywheel should i get???
OH, i also have another 350 block which came out of a 93-94 GMC 1500 ext cab would i be better off putting it in my car?? if so can i switch TBI to Carb on it just by changing manifolds? or do i have to do much more????
Re: swapping 1987 305 to older 70's 350 HELP, need info????
the '93-94 engine is a lot closer in design to the'87 305
-it has the same crank and intake bolt patterns as the
87 305-should be almost a bolt in
the '93 engine will also have a roller cam(87 305 should
too)
Re: swapping 1987 305 to older 70's 350 HELP, need info????
I would go with the late model. The early one is a very low compression engine. Just Transfer over your intake and accessories. May have to switch over the flywheel as well.
Re: swapping 1987 305 to older 70's 350 HELP, need info????
what kinda tranny was the "new" motor bolted to? i seem to recall something about the crank snout being different between auto and manual trannys. can someone confirm this or am i dreaming again?
Re: swapping 1987 305 to older 70's 350 HELP, need info????
Ok Yes the Carb and intake will swap out. Use your existing flywheel and clutch etc if the truck has a different one. There is a pilot bearing issue but I believe it is only with the 6 speed tremec.

the edelbrock manifold is on the early block will it still fit on the older block?? it also has a msd distibutor can i swap this also???
and also im getting a new flywheel and clutch kit any suggestions what type, size ,diameter, etc???
So everyone agrees that I should Drop the engine from the 1994 GMC Sierra 1500 into My camaro Right???
I'd use the later engine, personally.

No, you need the ECM to run the computer carb and distributor.

It'll fit the block, but it won't bolt directly to the heads. In '87, they switched from having all of the intake mount bolts at the same angle, to having the center two intake mount bolts on each side at 72 degrees.
A good plan would be to rebuild your '87 305 heads and put them on the '94 350 block. Better heads, although you'd still have the same intake mount issue.

Not if you're using a computer controlled system.

not to steal this thread but what would the compression be if the 87 305 heads were used on a truck 350?
__________________ u call it "drifting"? i call it a lack of proper traction, the fastest way around the track isnt sideways with the tires smoking (well, most of the time). oh yeah japan makes the best race bikes, but the cars are for transportation. and thats, your new opinion!

Stock replacements for the 305 application.

''(A good plan would be to rebuild your '87 305 heads and put them on the '94 350 block. Better heads, although you'd still have the same intake mount issue.)''
so Can i put the heads on and change the ignition/manifold over to the msd distributor with different intake and put a carburetor on it??? thus removing all the ecm and its wiring???? because i hate dealing with computer bullcrap....
and thats, your new opinion!
