What do you think of the vacuum modulator deal for the 4L60E? Ron put one in it this time, TransGo told him it would be a better deal. Hits kinda hard when you drop it into Drive. No big deal there. I still help him & his brother James with their Super Stocker some, and they like to borrow the dyno. Easier on gears & clutches than testing at the track. Free, too. <G>

Well In the beginning I was not sure of them but I have come to use them on any car I do not personally tune. WAY to easy for some one to make a slip and kill the trans in a heart beat! It has became a no brainer on High HP cars. It keeps 'TAPS" from pulling pressure out to soften shifts. On LS1 car I ALWAYS use them as they hack up a MAF faster then an LT1 guy can think about it LOL. Seeing the MAF is the main Trans pressure control on the LS base it just makes sense. I will [b]NOT[/b[ ship a blower car or truck with out one. The boxed tunning they ship with them is so crappy the trans is usually dead in a WEEK! BTW That Avalanch I had you do broke the rear end with in a month of us Building the trans. he has over 30k miles on it now He sent that box back to magnacharger and told them to keep it LOL

I say good call


Is your buddy still doing Ben Watson's engines? He has began making the show this year, and gone a round or two. That is a tough deal to crack. Frankie has picked up Mike's (Edwards) power, so he is going faster. Had a few bad driving weekends, but left on everybody at the finals in Pomona last weekend. Anderson just flat outran him, and everybody else. One of my old traveling buddies (Pete Peery) won Super Stock, nobody else hit their butts.
I get to thinking I would like to do that again, then Jeanie kicks me in the rear & wakes me up. <BG>

lil info on my current heads, they are lt1 afr 227's reverse cooled,,,a phone call to afr upon ordering them they can be cast with conventional intake bolt pattern and perimeter valve cover provisions,which throws alot of people off whom do not know ..I run a factory 94' optispark (no crank trigger) factory 94 timing chain (there is no options pre 95') its a lt1 minus intake,but a lt1 none the less...and for the real kicker its the oem matching numbers block that came in the car in 94' that I have utilized ... 98% of everything from tuning to chassis ,to actual engine assembly I done myself,the 1% being machine work that I didnt do the other 1% knowledge from a very wise 70's prostock racer..despite the idle jargon on what a lt1 is or isnt .Induction doesnt exclude it from being a lt1,the block itself is what determines that..gm only ran this casting from 92-97 and thier is no other like it...1 look from anyone that knows what they are looking at can easily distinquish whether its a lt1 or not.... Some people are more about doing more with less,been there done that...I for one and are most others,are about getting the most out of the factory gm block adorned in these cars.... If we all wanted to run S/E I can see keeping the car down with oem heads,and restrictive plenum....But if fast is what your after, you are only going to go so far.Then innovation and trial and error come into play...but ultimately the bore /stroke limitation in these blocks is the heel...so I guess its up to the owner and what they are after...

I also still use the original 4L60E trans.

Take care, Ed

Also had a 4bl intake & billet 4lb throttle body. Didn't look "very LT1". Looked more like an NHRA Comp Eliminator, Super Modified (single 4bl) engine with efi. Still very fast, just not what I expected.

I have a stock descreened LT1 maf with Mallory billet ends, I have been told the stock MAF goes static at 471 gps, is this the case? ANd if so is there a way around it? WIll the stock MAF flow 910 CFM of air and read it correctly? Engine analyzer pro says we use 910 CFM of air at peak HP....I am on the same track as you and want to do what you have done but at 3650 lbs, how much does your car weigh and are you on pump gas, how much RWHP does it make? ANd will I have the 4L60E "no shift" problem with a converter flash of 4000 rpm or so? I have the vacuum modulator installed,BTW I know I ask alot of questions, but I need alot of info. My Dad and I are building a kind of unique combo.

Thanks

David
