Re: Is There Any Cool Factor Left?? Are you kidding? The only motor that belongs in there is a 4.3... and we are lucky to have a special strong block, bow tie to step it up... I'd consider 3 liters enough displacement to do anything on the street... say 1000hp club... it just all becomes about...

Re: Reclocking kit needed Is that like a spring loaded baseball bat?

Re: does they have a differant engine block ?? Search "the holy grail of 4.3 info!!"

Re: problems with site? Yup it's the site/server... not user side... can't even get to page 3 in this thread.. been down from work too.. lol.. I'm sure our stuff is working... The external. .. we have 250k users we support so our end is up... lol. Does this coincide with all the syclone spam...

Re: cross counts And u can do the xylene trick to see if it fueling/timing issue vs mechanical knock noise. .. like hard plumbing lines bouncing against steel...

Re: Noob here with an 87 4.3 350whp. .. id forget the internals...imo really a low goal to go thru the trouble. A bit of a no man's land... I like the 3.8 idea.... nothing like a sexy spool but 4.3 or 3.8 would both be cool. So the standard response here is v8... a nice LS setup would be...

Re: Noob here with an 87 4.3 Boy... feels like someone needs to learn a lesson the hard way... Good luck. I would keep it simple... and not get a bunch of high dollar parts... What are your power goals? You sure u need to forge that motor out?

Re: 4l80e tear down and rebuild I feel for ya man... about how mine turned out. I know that book has a bad or hard to tell pic of the sprag and which way it goes. Just a thought. Been a year since I had my head in that mode. Also the servos are known to be weak and crack. If ur in there I'd...

Re: Where to get Johnson IC pump o rings? Or get a live well pump for fishing at Walmart for $40... or you can get more fancy but that's all it is...

Re: edelbrock 2114 question? My 2111 bolted right up to my old style. That 2114 should go right on the vortec that's what it's made for. All you need is injector bungs and a fuel rails to match. Oh and the hold downs. I mount ed mine off the 'carb' studs. Might have some decent pics in my...

Re: Quick Spool Valve - interesting idea So maybe turn the butterflies the other way... sort of. Like make a vane way away from the blades and don't close them off all the way. Not very effective but might do something... In my book sometimes simpler is better but I wouldn't want to stop...

Re: Quick Spool Valve - interesting idea I see it a bunch in the big turbo crowd over on the LS forum. Not sure if its worth the hassle, but that dyno chart makes me wonder. Most of the big turbo stuff is pulling on the top end as traction on the RWDs is already limited. Nail on the head...
