Noisy valvetrain, time to upgrade.
Noisy valvetrain, time to upgrade. Nothing has been done to my engine so I figured I should. What do you guys think of this combo.
xr269hr-14 cam with supporting springs, pushrods.
Ls6 intake
Probably a new oil pump and timing chain as well.
I figure these two changes will compliment the full exhaust nicely. I'm looking for another 30hp or so. I am really pleased with the performance now but everyone wants a little more.
I would like to keep the 2.73 gears.
Again, i'm not looking for 450hp cause I don't won't to blow up my tranny/rear, this is my 2.73 geared summer driver.

How about some GTP ported 241s with ls6 springs and stainless valves $800 shipped for the pair? i can get you set up with the ls6 pump as well and an ls2 or jwis chain, head gaskets, bolts, the whole number for a package price. I can also get you fixed up with the cam, pushords if you want them, and the ls6 intake.
Post specs of that camshaft.
By not even looking at the specs, I can see this thing may be a dog down low with a cam and those high gears in the back...especially with a stall convertor.

and im assuming on the cam its a comp cams xr269hr type.
prob 216/220 525/532 114...but i might be a little off. seems like a reasonable guess

Not sure it would be worth the work for the small gain on that cam. Go with a 224 if you want a little cam, lots of happy people with it! It sounds like you have some modest goals, you could possibly get close with just the intake and a tune. If you do have the front cover off, silly not to change the pump and chain. They are not expensive.

Yep there is a number of us with just cam's and Full exshaust and LS6 intakes that still have stock heads that run 12''s and if you cant get to the high 12's a full nitrous kit shipped is $422 from harris speed to your door. That imo is the best mod. Cheap and effective!
