I was offered an 88 Tbird 5.0 Sport Coupe, in good shape, plus a 350 Chevy with a TH350 trans for my TC... any thoughts?

How much do you love your TC? If it were me.. I'd turn it down.. All depends on the condition of you TC.. Also looks like you've got some work into also.. with mods and all.. just my 2 cents

Sport coupe has a whopping 155 HP with cast pistons, and power sucking and not that strong when stock AOD tranny. Possible to put in a 5 speed, and bring the motor up to 5.0 HO+ specs with a head, cam, intake, injector, computer swap, shorty headers, etc. The stock 2.73 rear sucks big time, and should really be replaced with at least a 3.27 or 3.55. Brakes arent real good compared to a TC, but can be upgraded, of course. If driven hard, it will suck HEGE amounts of gas.

Plus you'd be stuck with a 350 Chevy. You'd have to wait until summer and the lakes thaw out to use that. It's too cold to use it as an anchor now.

Ok let me ask you all this... If you could dump the same amount of cash into a 5.0 as a 2.3, wouldit make a difference? Performance wise or others?

What can you get for about $100. In the TC you could get 20-30 HP. What can you get out of the 5.0 for that. And the TC is still going to go as faster or faster than the 5.0, brake better, corner better, look better and still get 25+ mpg

As JeffK stated, the non HO 5.0 are really not performance oriented. I personally think you are better off keeping your TC, performance and definately looks wise. But, in the end, it is whatever you want.
