[QUOTE="Kritter, post: 31266, member: 164"] If you are interested my team will be selling a 2.8 race motor and a spare or two at the end of december. As for the motor, put a good set of rods and pistons in it, custom free floating rockers, offenhauser intake, port match the heads to the intake and exhaust and do a good valve job with new valves and pushrods, cam and thats all your gonna get. The 2.8s dont live with too much work. We have a full race motor and we have a motor with stock bottom end with custom heads as mentioned above and the race motor blows up EVERY time but the stock motor with race heads finishes every race. The stock motor doesnt pull like the race motor for obvious reasons...BUT IT FINISHES EVERY RACE... to finish first you must first finish!!!! If you are set on a 2.8 then you should email [email]kevin@dmsrace.com[/email] for more info on the sale of these motors. If it were me and you had a 3 liter limit I would go with a 2.9 and have Raider Engineering build it if you were on a "smaller" budget...Holmes has it in his 7s and it runs like a raped date! If budget is bigger for the motor go with an esslinger...275Hp and 250 ftlbs, no ford V6 under 3 will touch it and most ohv 4 liters wont either. Heres a response from Sven regarding a 300 HP and 275 ft lbs 4 liter either SOHC or OHV [i]"First, your power expectations are too high for a pushrod 4.0L.
