[TR] 6 cyl Camshaft Poll

[Chad]

Raymond-

I ran a Kent "Fast Road" cam in a '75 TR6 a number of years back. 
It had a 
milled head (about 1/8") and stock Z-S Carbs with a Pacesetter
header.

It was a SCREAMER!  I absolutely loved the way that engine sounded. 
In fact, I 
plan to put the same cam in my TR250.  It had a nice lope at idle
and pulled 
strong until I let off the gas pedal.

I recently asked for experiences and opinions on 6 cyl
camshafts on the 6-Pack 
list and didn't receive as many responses as I had
hoped for, so I thought I 
would address this list with the same question. For
those people who are on both 
lists, I apologize and ask that you just skip
over this email.

I am in the process of laying out the rebuild of my 2.5L
6-cyl and am trying to 
decide which cam would be best for my use. I know this
is a grey area for many 
people and opinion is easier than fact, but I think
the members of this list are 
probably the best resource available to help me
decide.

This is going to be for a street car, not a track runner. I live in
an area with 
lots of hills and winding roads, which I prefer over highway
running.

Here's what I have decided so far:
I have the late model engine &
head which will be balanced and blueprinted with 
the head ported and CR
raised to 9.5:1 or 10:1, and an aluminum flywheel and fan 
eliminator added; I
plan on the 1.65:1 roller rocker setup; I'll be adding EFI 
(haven't decided
on a system yet, but leaning towards MPI over TBI) & an EDIS 
system; 6-3-1
headers w/ free-flow exhaust system. I already have an A-Type 
overdrive for
those times I will be cruising on the freeway.

My early favorites are the TR5
profile, Richard Good's GP2 or TSI's S-2. The 
6-Pack list query has brought
another cam into consideration: Isky Z-19. If you 
have another cam you're
really happy with, please suggest it, or give me your 
experiences with the
above.  I will report the results (and my decision) once I 
have received all
responses.

Thanks in advance,
Raymond L. Hatfield
