I went 11.60s with a .030 o.s. rebuilt 318 in my Demon. Crank was turned .01/.01 and had stock rods, not even a resize, no replacement bolts, no balance, pistons were stock replacement Federal Mogul brand, a whole $80 for the set, and were .100 in the hole which was .02 deeper than the originals. Valve clearance was done with a die grinder in assembled engine, intakes only needed it. CR was 7.9 to 1. Heads were off a smog era 360 with a mild port job and stock 1.88 and 1.60 valves. Cam was a solid flat tappet from Racer Brown. ST-21--[254 at .050 and .520 lift]. 273 rocker arms. Less than $800 in that engine that I raced for 2 years and sold for a bit more than I had in it. Guy is still running that engine in a street car near 20 years later.

My 62 Valiant started it's racing days at the hands of a stock eliminator racer who wanted a cheap bracket car to practice in. So he found a cherry Valiant, dropped in a 318/904, and went racing. He ran it pretty bare bones, so I bet it was under 3000lbs.

Later, he sold it to a couple who raced it, but dolled it up quite a bit to attend shows.

Typically dialed in the 12.60-12.70 range, but I have no idea what the best pass was.

Welll.....we have a Slant guy who has gone low 10's with a turbo'd Slant combine motor. Bottom end is completely original except for bearings.

His Dad has a setup like yours and has gone mid 10's.

Will Burns has gone 9.06 on 5 cylinders with his turbo Barracuda.

It went 140 for speed on 6.

My best in my signature.

Not trying to burst your bubble here, but I doubt many people care, nor will it prove any purpose.

Putting way more power on a stock bottom end than it was designed to handle, is just a crap shoot. So it makes a 1000hp on boost before it shitz the bed........then what? you got a pile of scrap that made 1000hp before it broke. Not sure whats impressive about that. The next one may toss parts out at 700hp.

The point here is you aren't accomplishing anything other than luck of the draw.

And to be even more nitpicky........your bottom end isn't stock. You honed the block and put new rings and bearings in it. So now it's just a typical hot rod rebuild with mostly factory parts.

The guys who are harping about the "stock bottom end" stuff are the LS guys who are going to the junkyard, pulling truck motors and putting turbos on bone stock, untouched shortblocks and making stupid power........before they blow them to pieces

And my HP numbers above are just random numbers.......NO way I expect a 318 shortblock to make that power. Was just a random number, to explain that what one tolerates, doesn't mean the next one will
