1989 jeep wrangler

Engine!
Merlin 350 nodular iron block bored 60 over into a 360.
KB hyper pistons
Hbeams
Steel crank
Wold products mowtown 220 heads w/2.05 intake forgot exhaust and cc sizes.
Headers
Comp cams 286H w/hydraulic lifters. (should have done solids)
Comp cams full roller rockers, w/ 3/8" push rods
Edelbrock performer intake..(helps keep power band lower)
Demon 800 carb..
High flow aluminum water pump
Psc power steering pump
200A alternator for the winch and dual optimas (which suck btw) can never hold a charge.
Custom shertmetal snorkel/air intake.

Drive train
Custom built turbo 350 trans with manual valve body and 3200 stahl 10" converter
Twin stick np205 with 32 spline front output. 1410 rear yoke, flanged front
1/4" wall drive shafts
Shaved, welded, disc braked, cross drolled rotors, 14 bolt rear with 1410 yoke, and 4.88 gears, sitting under backwards xj springs

Shortened upper links and got all my brackets welded on tonight. No adjustment so lets hope it works,
Going to make new shock tabs tomorrow, i want to connect them to the top of my lower axle link bracket.
The ruff stuff bracket fit NICE, wish i had the $ to buy all the brackets from them.












More to come tomorrow, hope to be completly ready for shock oil, and nitrogen. I dont see any reason for not making it that far. :D
Getting pretty excited..

Got the hoops installed. They are solid. Going to try to secure grill to the hoops, as well as tie my stinger into the hoops, trying to make it as solid as possible.



Pic of the axle at full droop, i set it for 11" down and 7" up. Looks like every thing clears good. The extra inch the axle moved forward helped with clearances.



Got the brakes, installed on one side so i had to throw a tire on to see what it looked like...
Love it..cant wait to do the rear..
