1988 ford f150 xlt lariat long bed 5.0 302 auto column shifter
Oh my poor little 221 and 260's already forgotten as first thin wallsThe 289's were one of the first "thin wall casting" engines and were pretty much "before they got it right". Unless you are doing a numbers-matching or historically correct build, you would be ahead of the game starting with a later 302.
"cleveland" engine blocks or "cleveland" heads were Not used in Trans-Am or Can-Am racing,The T500hp Trans Am 302 engine were Cleveland engines, different animal. I ran a stock dyno tuned 306hp GT 350 engine in both my '34 Ford and '65 Ranchero and from the 1/4 mi et/mph they were over rated. Probably closer to maybe 275.
here's a trick old 1969 GW sbf 289/351 XE race block based build, 4.110" bore x 3.250" stroke, 345ci 3V with 600+hp...Any ideas for what parts to use to build a fast but street-legal 289?
