Need some help please? I am working on a freinds 69 400. The engine was a 400 2bl. It has a holley 750 vac secondary on an edelbrock performer. It is running full msd ignition, billet distributor with vac advance. Started out with 16 degree base and had to back it to 13 (can disconected). I am running the 21 degree bushing with 34 degree's total mechanical all in by 4,000 rpm. The engine has 150lb compression +or- 4 lb across the board. When we fixed the intake vacuum leak I pulled the pan to peek inside, cam looked good. It seems as it has a nearly stock cam with 20 inches of vacuum at idle. It idles smoothly runs well, but has no guts 0 none? We flipped off the guy on the unicyle that passed us! It's a 256 open rear end with turbo 350. Shifts twice every time. It will not even spin the tire? He has had the car 20 years never had any guts. Might try my carb on it next. Timing in earlier? sorry for the long post.
I guess I forgot the question? Am I correct in assuming this car should have enough to spin the tire? I think it should roast it. Should the timing curve come in earlier? If so what might be a good rpm to have it all in by? It also has a stock converter. Any recomendations? He drives the car on the highway, with an occasional long trip. Not concerned much about economy. As strange as this may seem (lol) he really wants to spin that tire. Not sure we want to go with a big gear?
Sounds like he needs to buy an extra motor and build something with the idea of what he wants out of it. That way he can enjoy what he has until the other one is ready and then just drop and run. BUT... be aware that more power will find the weakest link. So maybe not the first time he fries up those skins, maybe not the second time but sooner or later something else is bound to let go. Just a word of warning from another speed junkie. The more money you spend the faster you can go.
