Here my actual setup from when i rebuilt the top end and cleaned the bottom of my 69' 350 Block and pistons Heads bigger TA valves/ springs and porting (9:1) Gesendet von meinem D6503 mit Tapatalk
Got a custom cam from scott brown that works well with LSA of 112 and 224/244@0.50 and 485 lift Gesendet von meinem D6503 mit Tapatalk
Not directly for turbo but we keept a nitrous use in mind. The lsa should allow me a low boost application as well Gesendet von meinem D6503 mit Tapatalk
Yes a nitrous engine needs a lot of exhaust duration but a turbo engine does not. For a street turbo application the intake and exhaust duration are close to the same. If the turbo is on the small side for the engine to focus on low and midrange boost, the exhaust duration can be less than the intake.
For the "build" block i would consider a better cam of course.. Custom from scott or bullet i guess Gesendet von meinem D6503 mit Tapatalk
That is a good pickup for a mechanical fuel pump but for a big electric fuel pump like his A-1000 it's best to have "head pressure" feeding the pump so it doesn't have to pull it up hill through the pickup a few feet to the pump. These pumps are designed to push but not pull the fuel. So the best option is adding a sump to a stock tank so it gravity feeds the pump, or adding a fuel cell with the pump feeding from the bottom.
If I were to pick a perfect compression ratio I would use 8.5:1. Just start with the current engine on 7 psi and water meth injection and maybe add an intercooler later on.
Lot of great info here.. I am amazed by all the Expertise and help. Back to the subject.. Even though my decission is basicly made with the FiTech system Gesendet von meinem D6503 mit Tapatalk
Thanks for posting the cam card. 10 degrees .050" overlap is a lot for what you are doing All you can do for now is try it. It will be a learning experience. What we found with turbo cams that have large overlap is the transition from no boost to boost is abrupt and very annoying. I ended up advancing the cam as far as I could without having the intake valve touch the piston (.100" clearance) as a remedy. Our best 1/4 mile ET on gas was 7.03 sec @ 198 mph in a 3200 lb 49 Ford.
Well i think its gonna be a learning experience anyways... No "real" turbo kits for the sbb out there anyways. But thats what hot rodding is all about.. "finding a way to make it work.." I m sure it will be fun. Gesendet von meinem D6503 mit Tapatalk
This is what Crower came up with for me. It's a little blurry, but you can save it and zoom in.. Something different, but I must say that it seemed to work well..
I was not a big fan of having a sump hanging down low in the very back of the tank on a car that I planned to drive on the street. A simple smash in the back and you have fuel running everywhere.. JMO. From the A1000 install manual. Find a suitable place on the vehicle chassis to mount the Aeromotive fuel pump. Make sure thelocation will accommodate the pump mounting bolts, will position the pump at the half tank position orlower, It can be mounted on the frame rail below the tank.
jay , agreed . just thinkin about someone on a tight budget who already has an appropriate carb and wants to tinker and see what happens ( my guy ) . and even he is on the fence about the EFI decision with his budget considerations . plus some of us are in the "less electronics the better" frame of mind .
Back to the original question, I agree that the FITech coupled with a "good" EFI ready fuel system sounds like the way to go. I still want to try the Command Center for my low boost build but I'll make sure to read up on it a bunch first. And like Sean said hopefully by the time I actually get to this point they will have worked out the bugs.
As i said.. The command center has its bugs.. Thats why i would simplify with a good electric Fp and regulator ( got it used for a decent price) and as far as a fuel cell goes they very reasonable.. But thats just me i dont care about the originality.. Gesendet von meinem D6503 mit Tapatalk
Wow i see... Very reasonable.. Question if it works well with my aeromotive 1000 and regulator? Gesendet von meinem D6503 mit Tapatalk
