Building a Model A Modified Roadster, set it up for a SBC but I'm thinking of throwing in my Pontiac 428. Only problem is, I haven't built the engine yet and before I throw my money into it......I have about 32 inches of clearance from my firewall to the radiator. Anyone know if thats enough clearance for it to fit? I don't know how they compare in size to a SBC. Also wondering if theres any other issues with running a Pontiac compared to SBC as far as clearing steering, the frame rails etc.....so anyone who's thrown in a Poncho in their Rod, please let me know any problems or headaches you've encountered. I just don't like the idea of being another guy with a SBC in a Model A haha, thanks in advance!!!!
