if the car is a V-6 a bolt in would be a 2.9 out of a Ford Ranger or a Merkur Scorpio , which has a lower intake and stock 145 hp, and can be computor tuned up to 160 hp with stock engine , one more would be the 2.9 Cosworth 24 valve , same block but nice OHC heads, also a bolt in to the pinto , A C-4 or T-5 is a must because it is 200HP stock, mine is the stock 2.8 with the ranger/bronco II 2.9 crank made to fit, mild cam headers , and a efi tbi injection , but wish I just use the 2.9 so I would not have to adjust the valves , but very happy with it because it looks stock,
