if you found someone with a 460 from a truck youll be money ahead vs getting the lincoln engine. with the lincoln engine youd have to change the oil pan and exhaust manifolds- with a truck 460 you just bolt in and go (after you get motor mounts) as for the clutch assembly id just take the whole bit- bellhousing, flywheel, and the hydraulic clutch setup.
if your goal is 450 horse then yes you can get that with aluminum heads, a big cam, headers, a nice intake and a big carb... but youll have to revv it alot to make power. if youre just using it around town and have the money for aluminum heads, instead of buying heads id buy a 545 stroker kit. itll be way better on the street especially with big tires.

 

here is the thing with the hydrolic clutch set up. The truck I am putting it in is a mechanical clutch set up so it would be easier to use a mechanical style bellhousing. I gave you the part number on th bellhousing. If anybody knows if that bell housing would fit around my flywheel would be great.

 

i don't know if the truck rods themselves are any better than car rods, but the truck's rod BOLTS are better.

As for the bellhousing, it HAS to match the balance of the motor. an internal balance 460 with an external balance flywheel will have too much play and it probably won't disengage. an external balance with an internal balance flywheel. . . I doubt it would even bolt together, the flywheel is too thick. If it did bolt together i doubt the clutch would engage.

Now, you can use a hydraulic hellhousing with a mechanical clutch linkage. you just unbolt the slave bracket from the bellhousing and the mechanical linkage should clear everything. ALL hydraulic bellhousings will be for externally balanced motors.

The only external balanace mechanical 460 bellhousings were made in 1979 and and possibly 83. The 460 wasn't in trucks in 1980-82, were internally balanced before 1979, and went to a hydraulic clutch in 1983. Then to top it all off the 4 speed went away in 1989-90 (officially, it did hang on a little longer) whcih means you only have 8 years worth of bellhousings to find.

ok now if i think right some transmissions engaged from the passenger side. at least on the deisel trans it did in 87. not sure about the other years but i though i would say that I think i will have both bellhousings so I will just play with them and see which works best.

 

And at that power level (450 or so) check this out.

it's an 87 octane 460 that puts out 433hp at 5200 and 491 ft*lbs at 3400. Bump up the compression a tick and run a slightly stronger cam and I don't see why you couldn't have 450hp all in by 5500rpm on pump gas.

I will say there are some things they did in that build that don't make a whole lot of sense, but it shows you what these thngs are capable of.

Ok I had a brain wave tonight. What if I went ahead and installed a strocker kit that is ballanced within 5 grams! Then i could use a flywheel that is zero ballance tha would fit the mechanical bellhousing. I would have to change the ballancer on the front too but I am sure its going to need changed anyway.

 

anybody know of a good stoker kit that won't break the bank either?? cheapest thing I have found so far was 1,400 for a 521 coashthigh/ Probe kit

 

you can get one from www.cnc-motorsports.com for less... or www.adperformance.com is a couple dollars cheaper yet. adperformance kit is 1029 dollars, but you can piece one together for a little less than that. ive heard that coasthigh's customer service blows

 

try to find a place that sells a complete kit balanced.

Once you've pieced together a stroker kit and then send it out for balance and finish machining you're typically better off just having bought it from a single supplier.

Internal and external balance 460's use the same balancer, it's the crank spacer that's different. the externals have a counterweight on them while the internals are just a sleeve about 3" long.

I've seen where a guy just took an angle grinder to an externally balanced sleeve and then had it sent out with the rest of the parts for balance. I don't know if this is a good idea or not, but it seemed to work for him.

a new balancer spacer (weighted or not) is only about 30 dollars... i would just buy a new one if you dont have the right one to use.

 

Ok i think i have it figured out now. I am going to get the externally ballanced 460 from the truck and install a ballanced crank kit in it with a zero weight flywheel. The change the spacer out with smooth none weighted one. Buy the bellhousing for the internall ballanced flywheel and put it all together with my t18 trans and the np 203 or 205 trans i found(its the gear drive) Sounds like a great set up to me.

 

yeah, by doing that you can use the MUCH easier to find 351M/400 bellhousing and 390 FE flywheel.
