Re: 85 burb meets 6.0 lq4
Still cant beleve i cant find any dang headers that WILL fit. With tons of swaps done on 73-87 trucks no one sells them yet. I dont under stand why they are not made yet. Hell they even sell them for 88-98 trucks. That is crap they skipped one of the most popular body styles. Guess i will have to get fbody headers and hope for the best...

Re: 85 burb meets 6.0 lq4
I am also getting woried about my mounts i got. One diagram shows them to set the engine 1.5 inches forward of stock location. I have 4592 plates. Maybe i am just getting overly excited about all this stuff due to time limits i have to put motor in.....

Re: 85 burb meets 6.0 lq4
they dont make headers for that year if that is what you are refering to.. only S&P makes them for 600 bucks for mid lenght.

Re: 85 burb meets 6.0 lq4
you need to find yourself an extra day or two somehow. That way you'll have time to order something from Summit or somebody for O/N delivery for whatever you need. Like start Thur. afternoon and you can order till late at night. for Fri. and/or Sat. deliveries.

I will be trying the fbody headers and trying to get a set of maniflods from 6.2 liter or one like yours. They look sweet and i know what i have to do to make them fit. Will only have to notch frame lip a tiny bit. So i will have a back up plan if the fbodys dont fit.

Re: 85 burb meets 6.0 lq4
other then the exh. lift number that cam is a little milder then the GM Hot cam but hotter then say the '01 Z06 cam. So what are you thinking?
the thumper cams are more about the idle and sound, then about making big power.

Re: 85 burb meets 6.0 lq4

Re: 85 burb meets 6.0 lq4
I not really sure what i think i want good power. But sitll want to hear it some. Dont want it to idle like grandmas cadillac. But also dont want a 2000 rpm base idle. So far still going with the GM Hot Cam. Still a while away for cam purchase. Thanks. Is it true that the less lobe seperation angle helps carb motors get better signal to carb for better throttle response? Think i read that some ware.

Re: 85 burb meets 6.0 lq4
not sure...but my LSx motor guy suggested 112LSA for me...and he knows I wanted it nasty... but streetable.
by comparison....my cam is a 223/231 @ .050, .610/.617 lift, 112LSA. Using Patriots Gold .650 dual spring kit with bases, titanium retainers, keepers, and seals.

Re: 85 burb meets 6.0 lq4
68, that's a good tip.
Now is it long tube headers for torque and Shorties for high rpm horsepower or the other way around?

Re: 85 burb meets 6.0 lq4
Comp cams says the 110 will give choppy idle and better low end tq. Does that make cents to any one? I always thought the choppy idle cams were for top end power not low end tq....

Re: 85 burb meets 6.0 lq4
The amount of "lope" or choppy sound is the amount of lobe seperation you have.

Re: 85 burb meets 6.0 lq4
I liked the second article better. Think they both say the same thing tho. Looks like comp was right. Still up in the air about what one. I asked him how comps would compair to the GM Hot Cam. Sent him specs for it and waiting on a reponse. He has ben pretty fast so far. Thanks for the links. Now that i have read that i can remember learning that in school....

Re: 85 burb meets 6.0 lq4
you'll have to re-tune (and possibly re-jet/etc) that carb for your LSx when you install it. But at least you'll have your new fuel system in and taken care of so its not as much of an issue when you do the motor swap.
