how hard is it to get rid of that HT4100 and put in maybe a 350 in a 85 FWB? and does anyone know how much a new vinyl top for that car usually runs?

Thanks in advance

To drop a 350 into an 85 should be pretty easy actually. However, be prepared for engine mounts, a new tranny (dunno that the 4100's mated to the same thing the 350 does) and the electronics. Vinyl top, no idea.

It's not too difficult to swap a 350 in there, considering the 305 and 350 were used in 91-92 with no real change to the frame. Perhaps a better choice is a Cadillac 500 or 472 from any 68-76 Cadillac (except 76 Seville,) it will outperform any 350 and fuel economy won't be much worse since the engine doesn't have to wind out so much to move the car.

572" ported aluminum headed, forged internal, roller cam, stroker 500. :p

Crate motors are overpriced and suck.

Not always, I had an 84 V6 Cutlass that I intstalled a Discount Auto Parts 350 longblock motor. Paid $750 for the assembled longblock and put my own carb/intake/pulleys, etc..... Car ran great and the motor albeit stock save for intake/carb/headers/and exhaust was still pretty quick. Got a lot of trouble free miles out of that motor and when I finally sold it, it ran just as good. Here's a couple pics of that car.

They are not for me, I want to build my own. Some seem to think that they are so much better deal. Jury is still out on that one.

The cost gets so astronomical so fast on them. $10K+ on some! Come on!!

Still toying with the idea of dropping in my 455 Pontiac with a moded LT1 EFI on it for a daily driver.... Why not? It has a Chevy now, it has already been disgraced....

FWIW, was is the weight of the 472 and 500? The 455 is around 550-600 fully dressed. Maybe weight would dictate! Anyone ever drop an Port EFI into a 93-96?

Cad is still lighter than a BBC. An Allison V12 (1710CI) weighs 1160, but lord knows if I could stick one of those in my ETC or Deville I would do it.
