Just so you know, even with a chip the factory computer's proccessor is not fast enough to rev past 6400 to 6500 rpms with a load on the motor(You could probably free rev that high). Supposidly you can put a crystal in the computer that makes it faster, but i didnt find any real evidence that this fixed the problem 100%
Thats the main reason i went with megasquirt, and because of the fact that it was 600 bucks for something i had 100% control over.
What I'll probably do is set the limiter at 6500 and shift at 6300 or so. Even if the computer starts to break up after 6500, I don't want to take it past that since my car still has stock rod bolts, which would be my biggest concern.
Ford used to sell something called a RPM Extender, which allowed you to adjust A/F and the rev limiter. I'm not positive, but I thought it allowed you to wind the engine past 7000 if you wanted to. Don't quote me on that, though.
Like I've said before, the car may eventually get a stand alone. Depends on what I end up doing with it in the next few years, I guess.
So what your saying is you are making claims that have no backing just like the LS guy in this thread.
I think is rediculous for anyone to say the LS motor isnt a better design. It is, It should be, it has 40 years of technology behind it. There easier to work on than a SBF, have blocks that have been proven to last in 1000 hp real world combinations, and have cylinder heads that can be had for under 1500 bucks with your choice of springs, and good valves, that flow 350 CFM(at .600 lift, not .700). Its not magic, no, its technology, and evolution.
How about the fact that hot rod just did an 4.8L LS engine with very simple top end modifications, and a bone stock bottom end with an increased top ring gap that made over 1200 HP and lived thru 60 pulls on an engine dyno... The goal was to break the motor, they failed
A SBF could not do that without the help of an aftermarket block, it is questionable if it would have made it thru that test making 600 hp on half number of the pulls.
I agree with you, the LS is probably the "best"
factory pushrod motor ever produced. No argument there, and I would actually love to eventually have an LS powered something. But (and I know you've heard be give this shpeel before), throw in what can be done with aftermarket parts and it's a toss up between the LS and the SBF. There are so many similarities between the two engines, and in the aftermarket the tech gets shared. Hell, my cam's intake lobe is straight out of the "LS" section of the Comp Cams lobe catalog.
So, what I'm saying is:
Well built H/C/I 302 > Bone stock LS1
But if you're talking about a well built SBF and a well built LS, it really comes down to budget and block strength (assuming you don't go aftermarket). Everything else is pretty much a wash, assuming you know what you're doing.
BTW, what $1500 LS heads flow 350 CFM? Not being a smartass, I'm just curious. For a good set of SBF heads that flow that much (like a CNC TW R or a CNC Highport) you're talking well North of $2000. But being a Ford guy isn't cheap, that's one truth that's stood the test of time, haha.
