Was that in a 1/4 or 1000 ft track? 1000 foot track I might believe those times. 1/4 no way. I know Pontiac's pretty well after owing one for 10 yrs. and racing it for a couple years. It had a 400 HO with mildly ported heads, .465 lift/230 @ .050 Crane cam, Holley intake and carb., headers. It would get into the 13's on a real good day but most of the time was 14.00-14.10. 13.89 is the best I ever ran with it in the 1/4. I ran against a few 350 Pontiac motor equiped cars and blew every one away bad. Never saw a Pontiac 350 run better than a 14.50. I'm sure some have but they have to have a bunch done to them. Their design isn't performance orientated at all. Stroke on them is the same length as a 440 Chrysler so that means Briggs and Stratton postons and they have real small valves in all their heads because the bore is so small they can't run big valves and they are all low compression. To top it off they weigh as much as any other big block on the market. Remember all Pontiac engines use the same size block whether it's a 287 or a 455. If I had a choice I'd take a chevy 2 barrell 350 any day of the week over a Pontiac 350 4 barrell. I think this guy is yanking your chain. Did you see his time slips showing his Lincoln ran a 14.6? Also that Poncho would have to beat it bad to just break into the 13's. Dude I want you to know I'm not dissing you at all cause I believe your believing this line of crap this guy is telling you. I agree with Optik with what he said about the video.
I wish you good luck cause after seeing that pitiful looking thing you'll need it.
