I prefer the modified cars unless it's something very rare, like a few of our members have here. When I go to shows I spend alot more time looking at the modified cars than the stock restored ones.
AdamR makes a good point, you can go overboard in the modifications to the point where it's not a very good daily driver anymore. I battle with this often.
But I've also seen people driving cars with multi carb tunnel rammed big blocks, 590 lift solid lifter cams, 11.5 to 1 pistons, 3500-4000 stall converters as there daily driver through rain or shine,they just had to have a hoodscoop to cover the carbs up, but these guys are diehards and few and far between.
Adam I'd hate to see you sell your car, I love the look of that thing. What do you REALLY need to get it more streetable? With two kids you need a backseat if you ever want to take everyone for a ride, but if you have another car that's not really that important.
Your motor was pretty radical if I remember correctly, can you just drop in a smaller cam and some lower compression pistons to stay off the octane booster? or you could always think about trading someone for a rebuilt and more streetable 340-360, maybe even a mild stroker small block.
Let us know what you really need to make it streetable or what the problems are you running into with your current setup and maybe someone here will have some cheap ideas for ya.
Good luck with it, but think twice about getting rid of it!
