440 build

[Aron Gleason]

Im going to start buying parts for a new motor. Looking at the trick flow 270 heads with around 11.5 compression and a 690 lift roller cam. Stock stroke, mostly a wicked street car with occasional track time. Any suggestions as to other goodies i should consider for a potential 650 horsepower build?

So a 440? Pretty expensive valvetrain parts and high compression for the street, would make for a good durability test thread.

With aluminum heads, 11.5 compression and correct timing should be doable with pump gas.

I do like the extreme stock stroke builds.. so a dyno is in the cards?

Yes. But it's not something I'll get built by next year. It'll probably take 2 years for me to gather up everything i need.

What rocker arms would be a good choice? Hughes engines rockers that have been cryogenic treated or harland sharp rockers? What about lifters? I want a durable long lasting motor with very little maintenance. But at the same time I want it to be scary wicked.

Using alum rockers like HS on an engine like this invokes the 'big bang' possibility....
A 440 I built a few years back had the TF240 heads. Used the Comp steel roller rocker kit which came with shafts. Only needed a thin pedestal shim to get the geometry I wanted. Sol roller cam, 10.5CR, TQ carb, made 605 hp.
