Joel Vroman's 1967 Firebird
(In His own Words)

I've owned my Firebird for 12 years, it's the fifth Pontiac I've owned. I've showed and raced this car since I've had it. It's all steel and weighs 3290lbs with me in it. The trans is a T350 with an ArtCarr 3200 stall, 3.55 10 bolt rear. Car has run a best of 11.37ET at 118.3mph on pump gas.

I first heard of SDperformance thru PY forums, people seemed pleased with his work. I went with Dave because of the time he spent with me and his confidence in his ablity give me what I wanted. I went with his 260cfm street/strip port work on my #96 heads and his spec Comp cam. He's priced fair and what impressive work he does. I've dropped a second and 2 tenths with his combo. Highly recommended.
