Choosing pistons
Ok here's something else; you said
I would most likely be driving this car more street than track, and,Car will be tubbed and springs relocated
My 367 goes Zero to 93 mph in 7.92 seconds with a 2.2 60ft. The speed limit around here is 100kph or a tic over 60mph.Guess how quick this car might be to 60 mph, if I spent some money to 60ft decent? I'm guessing that would be a low 5 seconds.
Now try and guess how quick it might be with 500hp.
Well, I'll tell you; if you snooze, you lose. The turbo will make a difference in drag-racing for sure, and if set up right, can turn a very impressive 60ft. But as a streeter, with street tires and street suspension, here it comes; IMO, whether you have 450NA hp or 500NA hp is as good as moot.A win here can be as simple as rear gear and a tight tranny split.Even if you can harness the tremendous torque boost of a turbo, you still will be only a fraction of time quicker than the 450NA 360, pound for pound.
So here you are carrying around an extra buncha weight, with, IMO, no practical daily application.
See, I have had three different cams in my engine, from 270 to 292 degrees, and guess what; in first gear they were all capable of smoking the tires to well past the speed limit. And guess what else, the smallest was my favorite.
From 270 to 292 is a difference of 22 degrees, an easy 3 to 3.5 cam sizes difference. or perhaps 35 to 40 hp.And my butt-dyno was happy with the little guy.
If you want to better your ET, NO2 is a more viable idea.
Or better yet, turbo a teener. Build it up to 270 hp and and jam 12 psi into that guy. Now you have the street world by the tail. 18/22mpgs,or even 25Plus with overdrive, 87 gas off boost, and 500+ hp, unbelievable passing power, and with this combo a 4 speed auto would make sense.Tubs optional.
Look, the end result is the same, namely 500+hp. But because of the softer hit, monster tires are not required.Monster tires don't handle all that well. The 270hp build is cheap and easy.87 gas can save you thousands of dollars over the life of the engine.And the fuel economy means you can drive it everywhere,all the time.An overdrive would be icing on the cake.
Run it on 7 psi/400 hp as a DD and then crank it up on the weekend!
Oh wait, this is not your dream; it's mine.lol
