I have a 56 Chevy P/U and want to put a V-8 in it . My Uncle had his 99 Deville totalled out and it only has 82000 miles on it and I can have the motor out of it for $500. I have an 02 Seville and love the Northstar. I would love to put this in this truck. What would be involved and what else do I need off the car to make it work? I know it will take quite a bit of fab etc. Any advise would be much appreciated.

How much does that truck weigh? The northstar loves to rev but it's not real good for low end torque. So if it's much over 2 tons I'd go for a torque loaded pushrod motor. You might need a reprogrammed OBDI computer or a standalone engine management system since you won't be using the 4T80E. My advice is see if a 500ci Cadillac engine will fit in there... or be boring and use an SBC/BBC.

CHRFAB see their web site for hotrod swaps
wireing and CPUs are the biggest mess of work

chevy camaro or small truck v6 [2.8 3.4 0r 3.8] trans auto or stick will bolt up
[with a little grinding]
but sticks need a custom flywheel
not a eazy swap
and costs can go up quickly

swapping N*s a great thing, im actually doing the swap into my 1988 RX7, i am going with either a T-5 or a T-56 tranny, but the problem with mounting the N* longitudanly (sp?) is the tranny, the N* just can't pull a numerically low gear like the 6th gear in the T56; i believe you shouldnt go lower then .5 final gear.

but next big thing is the cost of the swap were talking $10,000 easy here you need a custom mounts, driveshaft, and the cost of the engine and tranny, and if you rebuild and make the N* even more potent were talking more money.

A rebuilt N* is around $4k, I can't see a trans costing more than $1500. If you're spending $10k you might be wasting a lot of money somewhere.

Custom work adds costs FAST
double what you first think
plus a lot of little stuff adds cost tooo
just wires and aftermarket CPU is $2000
custom flywheels are not cheap
then theres redues as some stuff just willnot work
even proven swaps like chevy V8s cost alot
add unknows in N* swaps and costs go up quickly

Again, $2000 for an aftermarket "CPU" is a bit much, because you could use a reprogrammed OBDI computer in most swaps, and even if you did need a complete engine management system they start at around $1500 from CHRFAB.

I'm pulling a Y-code N* from my '95 Seville to shoehorn into my Fiero. I'll be keeping the Caddy PCM & all other feeding and/or fed systems, along with the 4T80E transaxle. My Fiero needs a little "umph" since it's already sporting a Ford GT40 MKII body. The aftermarket engine management systems are OK, but not really necessary on the Fiero. I'll fool some of the systems (like ABS & RSS) so the Caddy PCM thinks everything is "normal."

I have a 93 allante, and I just replaced the radiator, last week for 700 bucks, and it still overheating, it appears that I am pumping exhaust gas into the coolent till it boils out and then heats up.

I'm told that I probably have to replace the engine to the tune of about 8 grand, does that seem about right, for a shop in central calif.? any other ideas before I go the whole route? is that "thermagasket" anything other than snake oil?
Help, I love my allante
