best heads/ cam combo
best heads/ cam combo what do you guys think? I am looking into getting a nice h/c combo and wanna see what you guys have and what numbers you are putting down with yours.
If you are in Houston, Tx give GTP a call. Craig's a great guy. I already had his heads and I'm finishing up a cam swap ( hotcam out/GTP6 cam in) and then I'm of to Creech to get it tuned I'll let you know how it does.
Even though I ran a set of the GTP LT1 heads for many years, I let Lloyd Elliot port my LT4 AFRs. I've never heard a bad word about LLoyd, and from my latest experience, he does some nice work at a reasonable price. IMO, there a some pretty reputable people that have stepped up and said his flow numbers are accurate. There's others out there who are doing good work as well. I wouldnt settle on GTP just because they were in town, unless you talked to them first a did a little research... (and talked to some other porters as well)
There are some good choices out there. I tend to be more interested in ETs than whether or not someone is nice. I havn't seen LE stage anything within 8 tenths of my H&C times. I'm probably going to get a set of CNC heads from Advanced Induction. Been looking into alot of companies, and they look to be one of the best.

The GTP heads were on my car when I bought them. I called Craig to get some info on them and they took care of me. I ran 11.60 with those heads and a pos hotcam. All I'm saying is that the heads have done good for me and their customer service is great (took care of my when I bought the cam). And in my book Customer service goes along way. And it would be an added bonus if the guy that did my h/c was in the same city if I needed anything.
I have a freind that has Llyods H/C and loves them and Lloyd has done him right. And another has AFR's and he's happy. So is there any right or wrong choice? I guess it depends on who you talk to.
No one that I know of has ever done a H/C comparison on a test LT1 it would be great if someone had the money to do it. What ever you decide let us know.

Some of the best times that I have seen were from the old GTP heads. They must have been doing something right. I agree, a reputable local shop would be the way to go. I just get concerned when someone says that they are "happy" with a setup. Sometimes "happy" performance for one, can be "sad" performance for others

It seems like every day, more and more high quality LT1 heads/cams come into the aftermarket. I have heard good things about Trick Flow, AFR, Patriot, Dart, and MANY shops that do OUTSTANDING port/polish jobs on LT1/LT4 heads.
As for cams, I really don't think you can go wrong with Comp, GM HOT Cam, Crane, or Lunati.
One thing I would make absolutely certain of: talk to as many people "in the know" as you can. It is very easy to mis-match components, and actually wind up with a dog that wouldn't keep up with a stock set-up.

T/ALT1 seems to be fairly close to you with heads from Lloyd.
My GTP heads were done back in 97-98 or so. Decent gains, but I never put down any stellar numbers with them. CC305 and Fastchip kept me in the high 12s... Heard some good things about GTP over the years, some bad reviews too, and I had an unpleasant experience with them a few years back and didn't particularly want to deal with them again...

The majority of the people that post recommendations do not list times in thier sig. As far as T/ALT1 goes, he is hauling. I may be mistaken, but I thought that he had run his best times with a different set of heads. I may be wrong though.
I do have one LE LT1 combo for you....Now there are some what ifs here so,
this is just an informational thing....
LE 2 heads
GM 847 cam
"Junk yard Short block" and I mean junkyard...we just rolled new bearings in it, left in the stock, dead rings...."New engine was in machine shop that year"
3750LB race weight
12 bolt
Yank st3200
11.85@114.5 with an auto
Dynoed 392 SAE unlocked through a 12 bolt...
Not a bad time for an engine we later found out had .036 down the hole pistons and .039 head gasket=zero quench and dead rings that kept the car going slower after every pass....
I'm sure with a fresh short block with good quench and some actual compression, instead of the 9.96 calculated compression, that 11.4-11.5 full weight would have been easy...maybe high 10's low 11's with weight reduction? Will never no as this engine is just a back up now...
So, these LE heads performed very well for the environment they were in.....
Great job Jimbob, that is cool to see someone slap a motor together like that and haul ***. I think your info is exactly what people are looking for. What heads, type of cam, race weight, and setup along with dyno #s and ETs with mph. Nice job with the junker.
