Default drag strip friday

A little back ground.I been working on a lt1 for a drag car (stock short block) with lt4 heads, zz4 cam, 1.6 rockers, 1 3/4 headers long tubes ,gm dual plane intake, hei, 750 dp,holley blue pump. 350 turbo, 3500 stall ,456 gears. I got it running and took it to the 1/8 mile track. The pass I made I shifted 6500 ran 8.062 79.?? mph. RAINED OUT . Back at the shop we was checking plugs little rich . Pulled vavle covers off to run the vavles # 5 both push rods broke. pulled intake to find push rods. I will have to pull oil pan off to find it.

Now this is the help I need from you all . I am wanting to run low 7s on the motor. Is my set up closes? what can I do to get there? stroker kit ? Bigger cam for sure. single plane intake ? port the head ? Thanks

Nah a stocker kit (I assume) returns the engine back to stock.. That would slow ya down.


but yes a bigger cam will help..

You do not need a stroker kit to get low 7s out of a much heavier car. See my sig.


IMO I would sell the LT4 heads and get properly ported LT1 heads and complimentary cam, and put a single plane on it.

In addition it is 208/221

I had this cam years ago and with a stock LT1 intake 6500 would be too high, with the dual plane that is probably WAY too high.

Steve,

We have a full CNC program for the GM LT4 head. We can also mock up and convert the head/manifold to work together at your specific deck height & desired chamber volume. Full CNC portwork, converting heads/single plane to work together, and porting of the manifold would typically be in the $1600-1800 range depending upon the amount of welding etc. we get into using your current components. Of course, we’re happy to quote you a complete setup if you need valve train etc. and can describe your goals. If you have questions or decide to move forward, we’ll be around. Thanks for your interest!

What was the point here? Are you jumping in, or are you still looking for other opinions?
