Thread: quick question concerning the 4.6

Tweet

That 80's trans am is a little differant from the 4.6 Mustang.
I didn't know you wanted to get that far in to the motor.
The old trans am's were alot easier to work on than the newer Mustangs.
My Big brother had one and I used to do all his work on it back then.
He had a small block 400 in his, and that thing flew.
Plus the heads on the two cars are totaly differant one is two valves and the mustang three valves, Plus hydrolic cam verses mustangs roller cam of today.
And the trans am had almost 100 more cubic inches unless your talking about the 455
engine then your talking 150 more cubic inches. This is compared to the 4.6 of the 283 mustang engines.
Can not really compare the two cars, It's really how much work you want to do and how much money you want to spend. Kurt
