hi, today i have just picked up a new engine for my 1966 coupe. I ordered the engine, and i was expecting a 289 hipo, but i ended up getting a 302 H.O.. what is the difference between a 302 and a 302 HO? my old engine i had was a stock 302. this new 302 HO, has been bord i think .30 or .40, and i know the cam is a comp cam with .480 int and .520 ex!, i am going to carburate the engine ( holly 670 street adv system) but then agian i thought i was going to get a 289, i saved the stock parts from the old 302, so i can put it on the new one, parts like waterpump, headers,ignition system and some other parts.will they fit? i also was hopeeing sombody could tell me what the codes that i pulled off the block mean (D90E-6015-ESA)(8626) tell me also what things i have to do to make this 302 HO work on a stock mustang.thankyou bobby wade

Where did you buy the engine? I think the difference between the 302 and 302HO is the year it was produced. Your parts should fit onto the new engine. The "D9" in the code means '79.

Waterpump, ingnition, etc. will fit. I had a mid 70's block in my 69 and it now has a new ford crate motor. Everything fit just fine from the intake to the oil pan. As JW boner said there isn't much difference in the 302 and 302 HO.(if any)

1969 fast back; yellow; weld wheels; 302 roller with GT-40 heads; 3:55 gears; 5spd T-5; MSD 6AL; E-303; flows; Hedman headers; Holley 600;
