I started building a lot of stock stroke 440 motors after that and had a guy down the street mildy port the heads and added 2.14 intake valves and 1.81 exhaust, all of the those motors with bigger cams(both hydraulic and solid lifter cams), not solid roller race cams, made over 500 HP on CA pump swill with single 850 CFM carbs and different intakes shruggy


Thanks Cab , i know its not new news, but
The above is what i wanted to hear,
Noone ever said it would be easy and
noone is handing out buildsheets of how their running
Low 11's on a stock looking motor , and driving their cars on street.
Time and money is scarce.
i Cant r&d for a year to get the right combo. Everyone else already has , i just
need to figure out how to extract the right info.
I appreciate the opinions so far.

Compression is not an option-
I have a 700 horse hemi motor in my 71 gtx now, but its race gas only
and im afraid to find out how streetable its not. It sucks up the fuel like No tomorrow anyways . It is very cool though . For the most part the car does look stock.
And when i get teched - Everyone suspects somethings up.
The hemi needs to get detuned , compression lowered, and
maybe it will be enjoyable on the street. Thats a project for next year- low compression
big balls.
For whatever reason Id like to hover around 1150's and have fun, because noone is competing with The fastest FAST guys unless they have a designated race car.
And my 4000 lb pig is not the car for this.


I wanted to offset the crank, but with the expense ,
I may as well go with a stroker crank .
I agree with the better rods
Everyone has an opinion on which head is better.


Mr Monte-
I generally leave my hood closed at dairy queen.
But its always cool to know that you cleaned someones
clock with all iron parts after they just spent a zillion
bolting on a crapload of shiny stuff from Summit.
and you just did it with cleaned up factory parts.
Those are bragging rights , and its always fun to hear people
say , wow Whats this guy with polyglas tires thinking . Wheres his headers ?
