My 88 Chevy 2 wheel drive Stepside

I've had my 88 Chevy for over 25 years I put a new 5.7 L 350 in it 18 years ago I flipped over the speedometer and put another two hundred and fifty thousand miles on top of that now it's time to rebuild my engine I will be upgrading to a 383 stroker with the complete Holley sniper package I have all my Holley parts now just waiting to finish the engine
