I bought the blazer in Feb 2014. Its a 1987 blazer with a 8.8 narrowed to factory width with 3.73 gear, on ladderbars and coilovers. The front suspension is all TRZ, with a TRZ rack and pinion, and coilovers. The engine was built by Mike Lough Racing Engines, its a stroked 6.0 in the above 400c.i. range with 12.2 compression, Ls3 heads that were worked by Frankenstein Engine Dynamics, BTR cam, 251/266@ .050 .639/.605 lift, vic jr intake and a 1040cfm prosystems carb. The trans is a th350 with a 8 inch 4500 stall from PTC.
