A 4 1/8" bore size in an engine block that began life as 3 3/4" in the 1955 265 engine is just pushing the envelope a little too far. AMC did the same thing in the early 1970's with displacements from 290 to 401 in the same block. MOPAR went from 273 to 360 in the same block with similar results. Ford- - - -221 to 351. I turned a 426 hemi into a 547 cubic inch truck pull engine by filling the cooling passages with epoxy, boring all the way through the cylinder walls in places, and installing flanged sleeves. It lasted for 2 1/2 pulls before breaking the crankshaft into 3 pieces. Putting big cubic inches in little engine blocks doesn't make good nonsense, no matter who is doing it.

My vote goes' to the 383, I built one for low RPM torque 'cuz I was gonna' swap it into my fiberglass Chevrolet, automatic, 3.08:1 rear end. I decided to leave the car stock but I'm keeping the stroker in case I have to pull the 283 out of my LCF and I'll have an engine ready to go.

Excellent info and opinion from people. With additional info I have found I am off the 400 and back to the 383. Hell I might even just go a 350, but I doubt it.

Transmission is done! Rear Suspension is done! Wheels are done! Bed bodywork is done! Soon to order a 383 crate.

A 350 is no slouch. It's tried and true, will run all day and give you years of service. I think what is missing here is your end goal for the truck, if you want a tire frying beast then a built 383 is the right choice. If on the other hand you want a dependable daily driver that will start every time and bring home a load of lumber with no struggle then look at at the 350... Just for the record, I would keep the 283, great strong running engine with plenty of power and can be built to run with the Big Dog's. I have seen 283's that can eat Big Blocks for lunch. Just my $0.02 worth.

Just does not return performance for the money spent. I am going to hang onto it. Maybe engine I buy will go into another build and I will rebuild this 283 eventually.

I'm going the other direction- - - -small bore, super short stroke, around 250 cubic inches, and enough valve springs and other go fast goodies to run all day at 8K+ RPM. Then it will go into a fiberglass body roadster that will weigh around 1500 pounds.

You have the knowhow and spare parts to play with combinations all day and night. Chuck a turbo on that 250 and see it shine.

While there are a few bad reviews, the overwhelming amount of reviews are very positive.

I was on the fence between a 400 and 383. Now that I have come to my senses I am on the fence between a 350 and a 383.

I think they are 90 days out. Here is some real money about to be spent!!!

If you are going to keep the 3.73 rear end I would go with the 350 only due to the shorter stroke.

78buckshot,

Good point. My ultimate plan is to go with a OD transmission. Probably sooner than later, but still uncertain.
