Okay, more opinions needed. TR6 engine rebuild will soon begin and I'm contemplating camshaft choices. I like the idea of improving the profile over standard but there are a lot of choices out there. I want a solid street machine and my driving style is to enjoy the lower rpm range while leaving high-revs to the guy at the streetlight. Thoughts, experience, vendors; all responses are most appreciated.
 
Thanks Shannon, good to know I can take your baby for a spin if needed. Hey, I went to Road Atlanta for the Vintage races today....awesome!
 
Stay with a stage 1 or 2 cam, dont go to "3" Check out integeral cams website, if it aint there you didnt want it.
Save your old lifters it pays to re-cycle.....

Hello 71TR,

from what you say,

" my driving style is to enjoy the lower rpm range while leaving high-revs to the guy at the streetlight."

I would suggest that the standard cam is all you need.

71TR,

I actually got to drive my TR a lot this weekend (put over 150 miles just around town) and I have to say that I'm very pleased with this cam choice (GP2). The idle quality is great with just a slight lope and I have lost none of my low end torque.. even with a lightened flywheel.

The GP2 is supposed to be an "Street/Autocross" cam with basicially means a torque cam. There are many cams that fall within this category.
 
I have enjoyed the performance boost offered by the Isky Z-19 grind in combination with a head shave to 9.5:1 CR. Be aware that high lift cams typically need bearings for the cam to ride on or you'll wind up ruining the block.
 
Good point regarding the cam bearing. Shannon, did you have cam bearings installed during your engine rebuild?
 
If you aren't looking for higher performance you might as well stick with the stock cam. Spend the money on a kick-ass sound system or a set of wheels or something.

No I did not. However, my cam doesn't have an extremely high lift so installing cam bearings wasn't a necessity. I did try to find a shop that could actually install cam bearings, but it proved to be very difficult. I did finally find a deisel shop that had the appropriate line bore machine, but I never actually got them to agree to do the work. You might have better luck in Charlotte (gee an engine shop in Charlotte? Go figure!). However, on the advice of my engine guy, I didn't have cam bearings installed. Based on my cam it just wasn't worth the extra expense. Besides, my car will probably see a few autocrosses, but that's probably the extent of hard drivin' (other than street hard drivin' that is /ubbthreads/images/graemlins/grin.gif ).

I really haven't admitted this yet because I wanted to see it run first, but I'm running 10:1 CR. So I'm making a good bit of my power through compression (with no issues so far, knock on formica). I think the combination of high compression and good torque cam translates into a fun street car.

Interesting... I installed a radio delete kit in my TR, I consider my engine to be the kick-ass sound system. /ubbthreads/images/graemlins/grin.gif
