Testing manifolds against headers on a high horsepower engine seemed a little of to me. Thats why my dyno comparison was done on stock 360 with a very mild cam. Headers were still worth a lot compared to even the best manifolds I could find.
But I missed it on the 5.7 having logs. My bad there.

Do you have the results of your dyno tests?

The summit ones are basically Hooker headers... I had them on a 1969 Bee with a 440 and they worked without too much banging. However, would strongly suggest TTI headers... Mine were worth the headache in money spent

I posted a graph on the first page, maybe half way down.

Wrong. I've owned Big Block B-Body sets from Hedman, Summit, and Hooker. The Hedmans and Summits have similar bend patterns, but they're not the same. The Summits are nowhere near Hookers (in bend pattern, or quality). The coated ones ARE identical to Patriots. The uncoated ones used to be identical to Patriot brand uncoated as well, although not anymore, as the uncoated Patriots have changed. I believe they are manufactured for Summit by them.

Now we're comparing header gains to an engine swap that uses current technology. I bet you dont find a modern hemi with computer,harness and all necessary pieces for the swap for anywhere near the cost of TTI headers.
For what it would cost to do all the swapping, I could build a nice engine that would perform better with headers.
Besides the O P asked about cheap headers, not TTI.
Headers are a proven provider of milage and performance gains. Feel free to not use them. Its a free world. A lot of guys dont like to improve their cars and think a carburetor designed for 70's fuels should run good today and points ignition worked fine 40 years ago.
Then there are people that dont believe in electricity either

Guess you missed the hacking a poster got for not running headers on his late Hemi swap in this thread. That's what happens when you don't read the entire thread before you comment.


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
