6.0 Swap

[N/ALS1]

@ skeet-Im going with the 373 becuase they are coming with the tru trac for a steal. I currently have the stockers 342's in now. I would like to go FI but I want to put my saving to a 66-67 Chevy II. I might have a deal on a true 66 SS Chevy II, the guy doesnt want to sell it but I think he will. It needs work but what doesn from that year? Its going to be a daily driver with extra hp, gas milage is not that important as I live in Baytown and work off of Fairmont. The heads are getting ported, thats the last thing he has to do before install. Where can I get a 4" tube from? Should the exhuast be duals with an x or will the ory be fine? The reason for the FAST intake is the article that GM high tech put out with a 5.3 and made some good numbers.
Appreciate all the help and input.

Nbs= 78mm
nnbs= 80mm Is that the only difference skeet?

FYI local guy about 7 yrs ago had a ASA cam in his LS1 fbody, 4000 stall, 410s and was 11.5s all day long. That cam can be made to work and work well. If you have it use it then later decide if a larger one is what you want.

if you want a good cam for a 370 then something in the high 230s low 240s will do wonders otherwise leave the asa in place. Youll need a good size stall for a cam like mentioned. Even the ASA will require a 3800+ to properly run
410s will work if using a 26" tire otherwise at track its going to lack

also most custom cams arent nothing more then a tweaked OTS cam. Pat G is known for this. when having your typical cookie cutter build 6.0 with 243s any big company's OTS cam will perform very well. everyone and their brother thinks they need a custom cam when they arent doing something different then what was done over and over again. Now a Gen IV setup will be more taliored to custom since its still fairly new. a buddy won Fastest truck this yr at LSx shoot out with a OTS cam. It was a 6.0 with 243 heads, GMT900 intake Tick performance Polutter cam, 3400 stall, 513 gears 30" drag radial on 100 shot it runs 10.4@127-128 on motor its 11.5s@119

Good info quik.
