Re: My speedtalk friends

Sorry to hear of this. There is very little anyone can say or do, we'll be thinking of you and yours during this very hard time.

Re: Ram induction question

IIRC the Dodge was one long ram per head, don't remember a common plenum. It's been a couple days :lol: Runner length is an interesting thing, and as noted by others in this thread, the runner has to be much larger to achieve the same rpm characteristic with more mass flow. When runners are long and...

Re: Hydraulic roller lifters tick only under crankcase vacuum

I'm betting it's the valving in the lifters, yes the clearance to bore is a bit high but I doubt that is the problem. Nothing to do with it being a ford but I just fought this problem on a 347 and lifter replacement was the cure, what sucked(no pun) was I had to do multiple replacements one at a tim...

Re: LSx and Gen-5 LT1 Tool Steel cam cores

Sounds great Mike, 5 at a time will definitely help for now. I am doing some bs "regrinds" on the LT's development right now and of course they will not live but I think they will make it through some dyno time. I will have more answers to what I really want after that. Thank You very much for your ...

Re: LSx and Gen-5 LT1 Tool Steel cam cores

Yes, thank you. This has updated my priority time. Since your are doing round core stuff, do you have anything in the works so we can use LT heads on a LS block? We weren't planning on it, but if you need more then one, we could make them, with our next run of LS cores. Thanks Mike, My plan right n...

Re: More power and torque for my ‘96 Chev 454

I've got one finished up on the engine stand . We went a little crazier on the build though. Ditched the junker preignition L29 heads in lieu of some alum brodix I had laying around , stroked it to a 496, used a long runner mercury marine intake manifold, custom cam, etc etc. All in the hunt for tor...

Re: Running an LS lean of peak at WOT?

Hopefully Mike can chime in with his thoughts. I am not in the cam business nor do I want to be, although I am not lean to the subject. I have my own stuff built for my own combo's and don't sell 100 cams a week. Besides that, people generally think you can take someone's numbers and have "your cam ...

Re: Running an LS lean of peak at WOT?

Do you already have an ecu planned for this project? Are you interested in a cam change to help control the heat? 5th cycle(Otto) style might work very well for you and improve fuel efficiency too, unless you need "bang on" torque down really low in the rpm band.

Re: Running an LS lean of peak at WOT?

Hello, What endurance environment is this? Marine or off-road? What is the RPM band you seek to run lean? Leaner than stoich should actually reduce EGT because the combustion energy is decreased, however I think that will depend on load. I've done quite a bit of lean cruise(up to 17:1 AFR based on 1...

Re: Lubricating the backs of bearings

On the flip side, there very well may be data showing dry is better but I don’t have the time to find it. I know what does work, so why question it. There are plenty of other things in the engine to question in the quest for performance or longevity. I could imagine heat transfer could make a diffe...

Re: 1000 cfm race Demon

Brad is good people, to expound...You can put any size carb on anything you want if you fix the fuel curve. The bigger, the better if you can fix. We have almost 15lbs of atmosphere to push into the engine, the more you can get into the pump the more you get out. Time is a factor, less restriction(b...
