Hey guys, I bought my mustang about 8 months ago. it is an 1986 lx with a 302. the guy who owned it had rebuilt the engine on the car. here is what he had to say about it: "MOTOR: is a 0.30 over 302 with forged pistons a new std. crank and bearings,the cam is an x303 with a 224 dur,and 542 lift roller with new lifters,felpro gaskets,melling hv oilpump,edelbrock intake,750 vac sec holley and bbk longtube headers,the heads are stock castings that have been ported and polished with comp cams springs, stainless ferrara valves185 in. and 160ex." Also the car has 8.8 rearend with 373 gears. rebuilt T-5. The guy said he dynoed the car at 281 rwhp!!! which I am wondering about. his combo after all this work put out only 281rwhp, I have searched through a lot of your posts and found out that you could get over 300 rwhp just by changing the heads to gt40 and the cam for example. is this combo missing something? does it need to be adjusted somehow, or this is what it should put out after what this guy did to the car? any help on this is much appreciated.
