383 stroker,perfect for 67-72's?

[eedgell]

Is the 383 stroker the perfect motor for our trucks? Does it replace the Big Block, and the other Small Block versions? With cam, and head options, as well as great rotating assemblys, is the block from a 350 sb all we need to make the perfect engine? I know there is more HP, and torque to be made with the Big Blocks, but when looking at performance, with mileage, is the "STROKER" all we need?

I LOVE MINE. it ran 16.79 @ 80 mph in the quarter in my 1972 lwb. heres my combination.
350 block, 400 crank & rods, srp 10-1 pistons,balanced, dart 2 iron heads w/2.02-1.60 stainless valves, double roller chain, roller rockers, towing cam, hei, q-jet with iron intake, p/s, p/b, a/c, 350 turbo w/shift kit, 3.08 gears w/posi. also get 17-18 mpg if i drive it nice.

The best point of a 383 is BB type power in a SB package and a SB price. There are plenty of packages and options available to build a 383 for just a little more $ than a stout 350 and still less dough than building a BB. Big blocks are still the best for all out power, but a 383 gives you plenty of power for a budget.

This is just my opinion. Others may have more to say.

I think the stroker is more appealing with today’s gas prices. I like the fact that there is a modern version (ie balanced assey etc) that takes out allot of the “work” in building one.

My car hauler came with a 396, and I ran it for years. I even freshened it up when I first got the truck and it was a great engine. I haul heavy loads and when I have bought junkyards, etc. the is literally cranked in the morning, ran til lunch, given a 30 min beather, and ran to dusk. The truck byself weighs 8500# unloaded.

I have been running 383 in my racecar since 1997, but I had never built a mild one for street use. About a year and half ago the 396 had got tired again, and I had a left over rotating assembly with a steel crank, KB flat tops and 5.7" SIR rods that I had planned to put in a street strip engine. I had a 350 4 bolt block punched .030", and built one for the car hauler with a COMP Xtreme 4X4 cam, a set of rebuilt 441 heads, and a 600 Holley. The truck has more power than the 396 ever did, and is way better on fuel. I got 6-7 MPG with 396 loaded, and I've got as good as 11 with the 383. It runs cooler and as heavy as this truck is, I could definitely tell a big difference w/o the heavy BBC over the front wheels on wet, slippery dirt roads going into some of the yards I go to in BFE. It used to push real when I tried to turn on those surfaces, but it better with SBC. I definitely don't plan on going back to the gas hogging big block.

i thought about it but why not have it all. i'm going with a 406 sbc

406's do not cool as good as 383's, especially in the application that I'm using it in. That's why GM never put a 400 in a medium or heavy duty application. They do make good street engines, but they are getting harder to find.

Built 383 from Lindvig Machine: Roller Crane cam and rockers 1.6 on intake and 2.02 intake valves. Balanced and everything to a fully assembled long block cost me 3,000. Not too bad. Putting Edelbrock air gap manifold on , the Performer not the RPM style. Edelbrock 750 carb 6Al box and billet distributor, long tube Hedman Elites. MOUSE

Perfect is a really strong word It's the best reasonably priced SBC package on the planet for anyone, and given the need for low- and mid-range torque in our trucks I can't think of a better all-around engine.

If not perfect. Then it is the engine GM should have built.

A 400 with 5.7 rods does good also

[BarryB]

I am building a 383 for my truck. I was making over 400 h.p. before I decided to make mine a stroker. I am hoping to retain the HP but increase my torque by a considerable amount. Making burnouts alot easier.

377. Thats what I'm building next.

[wibilly]

duece, your thinking a 350 crank as well, my 406 has 5.7"rods as well

Another, interesting idea is from the guys whom I bought my motor from. One of their motors was a 383 stroker, and bored out to 396. Didnt ask about their philosphy about it, but its food for thought:

[Billla]

A 396 stroker is significantly more expensive than a 383; the cranks are almost exclusively forged and require much more clearancing, a tighter ring stack on the pistons and typically a small-base-circle cam.

[Boog]

A 396 small block will have 'em scratchin their heads though.

I build engines for a living. I have built a number of stroker engines for my customers and was always impressed with the amount of torque they make. I decided to take the tired 307 out of my 68 LWB dailey driver and build a CHEAP stroker! I wanted to do a little REASEARCH and DEVELOPMENT for my customers sake. Here is what I did for fun. I found an early 2 bolt 350 block that no one wanted, bored it .030 over, bought the cheapest SCAT 3.75 stroke crank, resized some 400 rods with ARP bolts and bought the cheapest MAHLE dished 350 stock replacement pistons. I made sure the rod bolts did not hit the block,checked to see that the crankshaft counterweights did not hit the bottom of the pistons and decked the block to zero. Had my pal at the balance shop PRECISION BALANCE the whole assembly, and I put it together.
For heads I found a pair of 76cc smog heads and put 2.o2 intakes and 1.60 exhausts in and did some minor porting work. Camshaft is a crane 272H which is 216@.050 duration .454 lift. Intake is a Weiand stealth with heated crossover, holley vacuum 600 carb and an HEI with a CRANE vacuum advance kit.
This engine has 9.2 compression and pumps 165 psi on my compression tester.
I absolutely love the way it RUNSSS!!!!!!!!!!!!!!!! It starts right up, idles nice but still sounds like it has a cam in it. It just spins the tires. I can't keep my foot out of it!!!! I have my foot on the floor all the time. I feel like a fighter pilot looking for something to shoot at! IT DOES NOT COST MUCH TO BUILD ONE THIS WAY! JUST DO IT!

Are TPI's common on the 383?

Great post. This is fueling my fire for a 383 build up.

Dont believe the 383 ever came from the factory. As far as I know, its allways been an aftermarket thing.

Yes you are right...I was tired. This also requires "spacer" main bearings.

Around my house they are!!!

They put 400's in school buses. That's pretty heavy duty. Course they had superchargers on them.

A 307 is a 283 stroker (283 W/ a 327 crank). I guess you got a super stroker!

[forsale]

Can 92 TBI unit be ran on the stroker? Or does the computer need to be changed?
