I get 10-15 telephone messages left everyday and usually get back with peoiple with in a day or two also. Some people do not leave a PH # or area code (as crazy as it sound) and so these people never get called back. Some people do not leave a message at all so OBVIOUSLY they never get called back.

I work in the shop for 8-10 hours a day and ignore the phone to focus on getting work completed (completed work pays the bills, not phone calls) and after I get my work day in, I come in and answer emails and phone calls. This is pretty common for ANY porter, at least the ones that are back logged with work anyway.
lloyd-
i sent it to the one thats listed here on the site, i clicked ur name and went to "send an email to nighttrain66"
i will try again, or PM u this time.
Pretty much, i want to be able to run a 11.30 on a 383, and was wondering if u woudl recommend the 383 w/ ported TFS heads and a custom cam (but bret said he could not help me), or 383 w/ the LE3 heads and LE4 cam
This will be a street driven car, but I have rode in some pretty nasty-cammed cars on the street and did not mind it, which is why I kind of want to keep SCR down, so its not as rough on everything.

Yep, you have always gotten back to me within 24 hours of me emailing you, often within hours. BTW the heads are shipping out tomarrow.

On a side note, checkout www.advancedinduction.com

LE and Ai are two great sources for lt stuff
Try again, unported TFS heads flow 240-250 cfm. Hell AI's says their 200cc TFS heads flow 275CFM, while TEA's 200cc TFS heads flow 294 CFM. Hmm, wonder what the AI nutswingers will have to say about this.

I will second what Lloyd said about getting back to someone. Once again can't say enough about Bret and Lloyd and their desire to help us all out!

yeah, they do try to help as much as possible, but bret had never gave me a reason on why the LE package would be better than what i was looking at until today

Same thing you LE/BRE nutswingers should say when flow numbers themselves are raised - not a damn thing, because the numbers in and of themselves don't mean crap.

How are we nutswingers. Were not the ones bashing every other head out there besides the ones we run. I'll be one of the first to admit there are some badass AI cars out there, hell I almost bought a set of AI heads. It would be stupid to say one is better than the other without doing a test in a controlled environment though, theres WAY too many variables from car to car. Most of the AI stuff goes on cars that have the whole combination down, not just the heads and cam and thats why they post some good #'s like Rick Abare. If you guys would realize that there is more than 1 headporter out there that puts out badass heads this would all come to an end. And I'll admit I was skeptical about buying a BRE cam at first because some LE cars were putting down some pretty sad track #'s, but that came to an end when I took my car to the track. The LE/bre cars running bad times obviously have some issues to work out.

For one, I've got no issue with LE. If anything, he's been good for the LT1 head market and the subsequent competition he started by offering porting at budget concious prices.

Your comment about Ai/TFS flow numbers was silly, uninformed and unnecessary.

Wow, I didn’t know it was the head/cam guy’s job to make my car 60 foot better, make me shift better, make my local track prep better, and make the DA better. WTF, I got ripped off.

If the TFS heads are only 15 cfm better than a LE3 at peak, either the TFS heads suck, or Lloyd has his **** together(or both). But peak numbers hardly tell the whole story, what is the average flow difference on the two heads, I would really like to see that. And 15 cfm with all else being equal equates to between 30 and 40 hp.Or so the general rules say. At the max end of things 15 cfm is alot.

If the TFS flow 306@.600 I feel kinda bad about what I got.

What is the big deal with cutting the TFS? Not like it's a whole lotta money in the big scheme of things.


The LE 1,2,3 are well thought out no brainer packages. And make good power...but the ported TFS with a custom grind should easily make more power. All else being equal.

thats the problem tho, the LE3 would have higher compression, so everything is not equal
