http://www.binderplanet.com/forums/index.php?threads/1950-gmc-450-firetruck.123538/http://www.binderplanet.com/forums/index.php?forums/injection-tech.75/I added 89 GM 2 barrel TBI to my 50 GMC 450 series Firetruck with 270 ci 6. Used 302 military intake with adapter plate from Hamilton fuel injection. Also put on dual Fenton exhaust manifolds and modified stock distributor for HEI. Woke it up big time. 47 mph to 60 mph top speed. Good luck with yours. Bill at above link at Hamilton Fuel Injection is a tremendous source of info and parts. Jim
Also check out Deves post for converting Distributor to HEI. Very good post.
