Larry's car has: stock block, crank, rods, TRW stock replacement pistons, GT-40P heads with no porting, Edelbrock Performer RPM intake with no porting, 65mm throttle body, 1 5/8 shorty headers, and .498 lift hydrolic cam. Car made 356 rwhp. It should figure out to be a hair over 400 at the flywheel. I know it's not 450, but after we get the heads off and give the a little port job, hopefully it will be closer to that number. Car can run on 93 all day long, go to the track and run low 11's, and really isn't to expensive to build. My own car with a 30,000 stock short block and same top end made 331 rwhp on pump gas.
Thank you very much for the real world example.
My family's shop has put together dozens of motors like the one you just mentioned and those are the kind of results I would expect.
I will let FM continue to fantacise that there are 300 or 400 extra horsepower waiting to be tweaked out of such a configuration without a power adder getting involved.
Perhaps if he wants to refer to an all aftermarket engine with 12+:1 compression and a high lift cam pushing around 300 degree durations that can reliably spin around 7000 RPMs we MIGHT get close the 700 HP point he mentioned at one point in this thread. I'd like to see someone put and engine like that into their daily driver. Doesn't DrDirt have a configuration close to this? Perhaps he can tell us what kind of HP he is getting without a power adder.
Leave it to FM to argue that high compression pistons, large port/large valve aluminum heads, aftermarket headers and high-lift and/or long duration cams are not racing hardware. What are they then, factory replacement parts?
Refer to the Ford Mags and internet hearsay all you want FordMan. Next time I go to Daytona I will take my camera with me and take a few pics of some nice NA small blocks being put together for you that can really put out around 500 HP.
While I am there I will be sure to tell them about your mythical 700 HP stock block 5.0 so we all can have a good laugh.
