Todd, you can get ls1/4l60 combos for under $3k. I have yet to find that deal with a t56
They've been available for $3,000 and under. Just have to watch for them.
$3000 - 89K
$3000 - 130K
$1800 - <70K (Member here)
Well. I am familar with the LS1, I happen to have two of them and one I had
to yank the intake off to fix the coolant line underneath. The GTO they deleted
this odd design flaw. I just have not installed one of them into a 2nd gen (I did
not want the added hassle).
One thing I will say about the LS1, I do like the intake manifold design. I have
always hated the all inclusive intake/valve cover Chevy engine had. Its nice
to see that after 47 years they caught up with Studebaker and separated the
two. I never knew how spoiled I was growing up with Studebakers and that
fuel-only intake design. I laughed when the "airgap" intake came out years ago
for the Chevy V8, "Hey! Thats just like Studebaker!" (kinda - still one piece).
Kudos to GM for finally getting that right. When I got the intake off the LS1 I
had to take a picture of the valley cover.
gm is still cranking out f body pans, because they know they get bought for swaps. i bought mine from the dealer. if the h3t pan(aka gm's universal rear wheel drive swap pan) was available at the time i'd have used it in my impala.
Yep no fear of an fbody pan shortage anytime soon
Stock Truck manifolds will not work, you'll need F-body manifolds.
A 5.3 is not that much cheaper by the time you get done buying intake and exhaust manifolds, accessories + accessory mounts, oil pan and water pump.
The 5.3 is 325ci not 327ci
if your going to keep it EFI be sure that if your doner motor has the knock sensors under the intake rather then on the side of the block to replace ther rear sensor and use the updated gasket as this is a big problem
The 5.3 can make 400 hp at the crank with a cam and valve spring change but if you keep it EFI you have to change the rev limit do a search I believe Car Craft did a write up on it sometime last year
Also if you get a 5.3 out of a monty SS or h3 alpha they are aluminum as well
Just my 2 cents
GM Dubbed it the LS327 when used with a performance cam.
Its not the first time, nor the last that displacement numbers will be fudged to make a motor sound cooler. Ford 5.0 (302) was really a 4.9. '70 Camaro was called a "396" even thou it had a "402".
I thought the FWD motors did not make good swap candidates?
