I was eyeballing the crossmember kit to put a AMC V8 in it, $360 + $100 core for the old, so $460 cause I wouldn't give that up... for right now, I'll drive it as it sits, but in the future, I may go EFI 4.0 w/ a 258 crank, which makes a 4.5L engine that the EFI computer will still understand. the 196 is a decent motor but if it needs rebuilt at any time, pistion cost will make the rebuild a bit pricey.
