pump gas 451

[Challenger340]

Been lots of bantering about engines/combos over the past while.
That's all fine and dandy, whatever "floats a persons boat" is just great by me. All the power to everybody with BIG bankbooks.

But, just for shits & giggles, here's a nice "cheap little stroker motor", thats probably more than capable of putting a smile on most guys faces when "ya hit the loud pedal", and, keeping in perspective, costs FAR LESS than many strokers being contemplated by many.

Also keep in mind, without Big Budget AFTERMARKET BLOCKS, just how much power can those stock blocks actually take ?

I do tons of stuff from 500 inch to 572 inch, albeit, all with aftermarket blocks at 800 to 950 H.P.

IMHO, for the stock blocks anyways, stay to under 600 unless you want not "IF" but "WHEN" you stuff is "garbage" exiting stage bottom out the oilpan.

Just how fast ya wanna go ?

pump gas 451 with VERY USEABLE Torque down low, decent horsepower up high, on easily done EDDY heads, with a DRIVEABLE CAMSHAFT that you can actually "toodle around on" in traffic !

Nice #s, i'm guessing its a low-deck combo.

Heres another on the cheap  (total cost about 3500.00 carb to pan including the purchase of the block)

This combo ran 10.91 @ 120.56 on a 1.51 60ft. in mine shaft air.

Changed to a comp custom solid 543/529-250/256 @50 on a 108 LSA
Weiand TR, 2 600 holleys, bowl blended the heads myself) ran a 10.87 @ 123.58 on a 1.61 60ft. in the heat, first & only run with no tuning.

This was at 3100 race weight.

It was more pump gas friendly with the larger cam, but with the iron heads i ran 110 to be safe.
