You know, I gotta ask you.
Can you do this kind of work, or do you pay somebody to do it?
Because if you can do everything involved to swap out an engine including modifying/building the mounts and an exhaust to finish the job, then
A. you're wrong
Anybody typically attempting this swap isn't looking for a "bolt in" solution.
Before anyone even considers this swap I'd imagine that It's taken as fact that they will have to build/modify mounts, a driveshaft and a set of headers to finish this job.
W/ the headers being one, (which I can do) and the drive shaft being the other (W/ the last time having to have one shortened was my current project @ $100.00) Where do you see the additional work that negates the worth of doing the swap?
I just put down the Summit book.
Pg #128. Bluprint Engines 383.
420/hp/450tq.
4 bolt GM block,Scat cast crank, hypereutectic flattops, Aluminum heads, GM rods w/ 150k psi bolts, flat tappet hyd Cam, lifters, alum intake, edelbrock carb, MSD hei dist, 30 mo. warranty
Fully dressed is listed as turn key, 3995.00
Then turn back a page to the 347
330hp/380tq
comes w/ the same as above except has
cast iron modified heads
And of course, the 2 bolt block.
same 30 mo warranty
The "budget stomper" is listed 3995.00, but you still need stuff.
(*Do you consider this the same just because the price is the same?)
There was a fully dressed version of the 347, but it was listed at 4899.00.
I didn't include this price because blueprint couldn't justify the additional expense. ( I called and asked) But know this. They say when you get it "fully dressed" it also comes with a w/p, mechanical fuel pump, plugs and wires. I decided that I could buy these items for less than 900.00
So bottom line, The budget stomper still needs a w/p, plugs, and wires at the 3995.00, so we'll say an additional 100-150.00 say....4150.00
or look on page 129, FRPP 306 340/310
stock crank, Comes w alum heads and hyd roller, forged pistons, but no intake, dist,carb wires, to consider it "fully dressed"
Warranty???
3839.95 And it's missing all that stuff, still only a 306.
(* Is this the same price to you?)
Or If you just wanna be a determined to get it running w/ a chevy kind of guy, Then look at the GMPP crate engine on page 126.
350c.i 290/332. All stock new crate engine w/o carb or dist.
$2579.95
Find me a SBF motor that makes 290 hp, factory built w/ new parts and comes w/ a warranty for the same price as that.
Then after you find your ford motor, find me the transmission you're gonna back it up with.
PG. 198 has a PA turbo 350 w/ converter rated to 450 hp priced at 904.00
The next page has a PA C4 w/o bellhousing/ converter rated at the same 450hp. priced at 1147.95.
B. If someone considers this swap and has to
pay someone else to make it fit,........Then I'll agree w/ you and everybody else, that it is not cheaper.
Man, I'm gonna have some stickers made that say that. I've never heard that one. LOL!
Besides Z06 emblems look stupid on mustang fenders.
. It's one thing if an LS1 or LT1 is in a GM car (Bel Aire, old Camaro, etc...), but to put that engine into another brand car (Fairlane, Mustang, etc..) is just overdone and lame.
