Trick Flow Heads and intake

Post  BigBoy460 on November 10th 2012, 12:42 pm

Ok so I have a 460 that was rebuilt 1 year ago and has stock 22cc pistons and I am rebuilding the top end for street and strip application and I was wondering how well the trickflow heads and intake would work with my stock 22cc pistons and a qft carb 850 cfm and what cam would you recommend with this application if I am trying to reach 550 to 575 horsepaower for street and strip

Would this trick flow heads and intake be so radical sounding,,, i want it to sound good but also want it to be smooth aswell........................

The "radical sounding" and rough idling is a function (by-product) of your camshaft, not the heads and intake manifold you choose. The Trick Flow Street heads, also known as Power Port 290, would be an excellent choice along with their 4150 intake, or the Victor intake. If you are more concerned about the street application, then use the Torquer II manifold or some other choice.

First ... those heads would be a good fit for your application.

Second ... getting to above 550 horsepower with what you have and still being an everyday type street vehicle would be a "stretch" with ANY camshaft.

Third ... I would run a custom ground solid flat tappet camshaft in your application to get the most from what you have.

X 2 on what Randy said. And I would touch base with either Randy Malik or Lem Evans on the camshaft selection. They both know better that what I do, in regards to what would work in this application.

In regards to the camshaft on a street strip engine,,,it is the amount of overlap that creates a poor idle, and the amount of intake duration, more so than exhaust duration. So, to reduce the overlap, what the cam designers can do is increase the lobe separation angle.

When you tune the engine, get a new BIG vacuum gauge, hook it up, just lay it on the intake manifold and tune for vacuum at idle, and at off idle. In other words, adjust your carb and distributor for increased vacuum readings on the gauge.

Hope this helps,

Charlie

Do you recommend any bowl work or cleanup on the TFS 290 heads for under 550HP application? Would it make any difference in street application?

If you are talking to me, then no sir I do not recommend any bowl work or clean-up on the TFS 290 heads for the street, BECAUSE they already are nicely finished in that area. Better than any other heads on the market.

If you were to have mentioned most any other brand of heads, then heck yes I recommend bowl work and clean-up.
