I am looking for a motor from a 5.0 mustang from 87-93. It could be just the motor or the whole car would work too if its for a good price, even if it is totalled.
.030 is widely recommended as the maximum for a 302. Some people have run plenty of power in a .040 over block just fine tho, but like you said for how long?deadsp0t said:I understand some of those are .040" which can be ok but aren't going quite as reliable in the 'long-term' as .020-.030 blocks. Be sure to ask.
Yes, in most scenarios the thinner walls are the issue. Even with a stock stroke it 'can be an issue' causing cooling issues. It's not always an issue, a lot of ppl never have an issue. Like you said earlier its just the recommendationI think the real problem with over bore motors is when you stroke it and get a poor rod ratio, more force on a thinner cylinder wall equals trouble over an extended period of time
If you're going to pick up a used motor look into the 5.0 explorers and mountaineers. Basically cobra motors with the exception of the cam.Probably somewhere around there. I talked to a guy at Dallas mustang and he said you can find alot of totaled cars and get them for $500-600 and just take the motor and scrap the rest.
