I just purchased a 1930 Model A with a 3.3l Chevy V6 engine, and TH350 trans. I'm considering swapping (in) a 4.3l Chevy in place of the 3.3l. Can anyone tell me if the engine mounts are in the same position on each of these engine blocks? And secondly, Do each of the engine blocks have the same engine mount bolt pattern? So in other words, can I just pull the 3.3l out, and bolt the 4.3 in it's place?
I know that the engine mounts are physically different on the 3.3l's (1978-79 Malibu's only), and the mid-80's to early-90's 4.3l engines. But, my Model A uses a TransDapt (type) flat, 90 degree mount bolted to the engine, and a 90 degree mate, welded to the frame.
I'll get the correct flex plate, as well as all other external pieces, including distributor. The 3.3 is of course, is carbureted, and I'll replace the TBI or CPI on the 4.3 with an Edelbrock manifold and carburetor. No computer/wiring issues here.
I know, I know, I know....the question most everyone asks is, "why not put in a V8?". Well, because A) I love the way the V6 sits in there, with space to work on the engine, and B) I don't want to lose ANY firewall space (I'm tall!), and C) I have other cars with V-8's, including a Corvette with and LS-2. So, if I want speed, I have it I just want a little more power in the Model A, which is a "cruiser".
