Going Turbo LSx '69 GTO Judge Clone

[2165 Turbo Rail]

just remember to overfill the oil!

i still like your car, and there is no such thing as too much power, just inadequate traction.

I have everything except a gasket set for the 2.3t. I hope to get it built before too long. I guess i should start the build thread i was going to start a year ago.

werd!

[2165 Turbo Rail]

yea, theyre picking it up next weekend. Its being shot for rod and kustom Monday

btw, looking forward to seeing this car back on the road. I have always enjoyed your progress on it

awesome.. congrats (hopefully)

plans kept changing and I was going up and down and this way and that way....

I wanted to build a short block so the car wasn't stuck at John's house very long but just couldn't find everything for a decent price

This stuff is a 4" crank, 6.125 rods and 3.898 pistons... (that's the kicker)

so this is going to end up being a 382ci 6.26 liter meaning I'm taking a 5.3 and boring it out to a stock 5.7 bore

this way I can take my short block and fix it correctly this time and then have it as a spare/next project/ or sell it

I've been ready for a change so this is deff a change... should run good too

I assume you mean a 350? Stock bore size on one of those is 4.000.

stock bore on a ls1 5.7 is 3.898

from Wiki
The Generation III 5.7 L shares little other than similar displacement, external dimensions, and rod bearings, with its predecessor (LT1). It is an all-aluminum 5,665 cc (5.665 L; 345.7 cu in) pushrod engine with a bore of 3.898 in (99.0 mm) and a stroke of 3.62 in

LS1 is a 346 Cubic inches stock. Not actually 350

right but I'll have a 4" stroke instead of the 3.622

4" stroke
3.898 bore
8 cyl
= 382

d3rp on my part. What did they put those in? I thought most early 00's LS engines were either 4.8 or 5.3.

In short you used longer rods?

LS1 proper is a 5.7

4.8 and 5.3 are LS based but not really ls1 they are something else.. like my 6liter is LS based but called a LQ4

4.8 and 5.3 came in trucks

[2165 Turbo Rail]

nope.. .stock rod length but stroker crank.. going from 3.622 stroke to a 4" stroke

Aftermarket crank? Do you gain more power from a bigger crank? I presume the crank gives you a longer stroke in the cylinders

yes is an aftermarket forged Callies crank... more torque mainly but it completely changes everything so its hard to compare really

yes the crank gives you the longer stoke... longer rods would not because its still going in the same size circle on just further away from the crank... the crank is actually going to be "bigger" meaning the rod connection point on the crank will make a larger circle

Got ya! If your running a 4L60E TQ isnt a factor with that trans. I love the 1st gear ratio out the hole with that trans. 1.52 60fts here on Drag Radials with 3.42s

Another way to trick the engine into thinking it's got more cubes than it does is to increase rod length. Some race engines are limited to a certain engine size so they mess with the rod length if they can. Most sprint engines are going to a big bore short stroke setup though, as torque really isn't a problem with these cars because they're so light.

I've broken it twice already with my old set up it supposedly is very well built now... the place said I shouldn't be able to break it.... we shall see LOL
