Couple questions on 87 5.0

[moc]

that our stangs came with a steep gear like a 4.10 (4.11 is a cheby gear ratio) but the sad fact is yours don't .and as far as top end goes it is limted with a fuel shut off !( even for a speed density car like yours) don't quote me on this but it's like 127 I think . see that 82 did not have a computerized shutoff yet ,thats why he was able to attain a speed like that ,also you have a tag on the outside of your rear housing (pumkin) that will tell you your ratio . 3.27 were an option on the police modles , but if you have an auto ,you have got the worst gear ratio there is ,2.73:1
