This is just a photo of my 1987 Buick Regal Special-T (Olds 307 V8, 4-speed 200-tranny, and limited slip rear with 308 factory gears) that my D&S Performance 1973 Buick 455 goes in next month (waaay too much snow the past month to do anything the way I want to). The 10-bolt 8.5" posi-rear (behind the Regal) came of a 1984 Buick T-Type Regal with the stock 3:42 gear ratio (TA-Performance's aluminum rear cover has already been ordered). Second photo is of my TA-Performance long-style Buick 455 headers, remainder of my 3" true-dual exhaust system, aluminum radiator, etc. The last pic; when I bought the Regal, the prior owner had 2-1/4" true-duals installed ... and lucky for me, I do not to worry about the cross-member having to be modified. The 3-1/2" header collectors clear easily ... thank God. Additionally, Dan Smith had me ship the Edelbrock Performer intake to hims so he can port-match it to my Stage-1 heads. Dan also had me ship the TA-Performance Street/Strip Mechanical Fuel Pump to him so it can be installed correctly (I have TA's double-roller T-chain in the motor). I also ordered HUGHES (#HP2235) th400 locking dipstick. My last 2 Buick 455 Regals (same Buick 455 Pee-Gee Performance built that was used in both Regals) caught fire for NOT having this. The 1st one burned to the ground, and I saved the last one. Thanks for your time, help, and for being "Buick-Guys." Lata.
