383 Stoker

[SunlitComet]

I really need to get a ht383e. Badly.

 

[bowtiefreak]

I really like mine. For the dyno sheet want the before tune or after? let me guess....both?

 

[SunlitComet]

Are you kidding?

 

[bowtiefreak]

Here is the after, still looking for the before tune sheet. I think I have one somewhere that shows both graphs

was gunna build a 383 for my 96' but i couldn't bite the bullet to see my hoe out for 3-4 months being that it was going to be done in my automotive class at the local community college. Looked around the junkyards and could not find a vortec motor. The only one i found and it threw a rod and blew out the cylinder walls. Good luck on your build!! Hope to do the same in the future.

Nice gains ESP since our motors stock is like 240hp at the crank factor in the 30% loss hp in drivetrain I think is the average ( correctme) and a stock Tahoe is like 190 maybe to the wheels give or take I want to do this but don't have the bank yet

Eventually i will be getting a 383. Prolly going to get the ht383e from the gm website. Dont want to max out my fuel to have it though. Still searching on what i could do to change out the fuel componits and the intake system. Not sure what i want to do there either...

Anyone changed out the fuel stuff to get more fuel to everything? I dont mean on the stock system. I mean like a different fuel sender and such. I dont want to have to max out the stock system and then need more for a supercharger later on or something. Know what i mean?

 

[SunlitComet]

the stock fuel system can handle the ht383e. even with a bbtune to take advantage of it

Is doing a 383 stroker the best way to build a vortec? Cuz im about to rebuild mine...

I stroked mine back in 06 with a lunati rotating assembly. I had a local shop machine the block and I assembled it. I kept the topend stockall those years until now.

added built tranny, TCI SNS 1800-2000 stall, edelbrock etec 170cc heads, COMP roller rockers, COMP CAM 268xfi, upgraded fuel system to include wynjammer.com custom 46.7lbh spider injection upgrade and a PCM4less tune.

This saturday I'm heading to the dyno for a before and after and I'll post it asap.

All togather I spent:
Heads 1100
cam 280
rockers 320
Trq Conv 680
flywheel 600
Bottom end w/machining 2200
tranny build 1800
tune 400
gaskets/oil/sensors/ect. 400
total $ 7780 and man can I tow!

so after buying a 99.... replacing all steering components and installing a 6" lift I drove it home from my families shop only to blow a head gasket and find the intake manifold leaking as well (in 2 miles under 40 mph; I know not relevant) I started looking at options. Considering i have 139xxx miles on the rig i looked into replacing the engine as apposed to fixing the issues.

5.3l swap.... too much headache for my time frame and still end up with a junkyard dog with 100,000 miles on it.

stock replacement (NO GAIN) 1900 summit or jegs

HT383E 5000-5500 depending on where you shop

Consulted a local machine shop who has built a motor for my jeep many years ago said he could do a 383 to the Ht383e spec (parts and labor) for 1615 out the door.

So if you are mildly mechanically inclined you could pull your block and have it built and save a ton.

Also (for sake of post) I consulted a shop about R&R and they said 800 plus fluids

grand total doing it your self or with help of a shop.... 1800-3000ish

Shop your available machine shops and ask around word of mouth is a great indicator of quality
