Max HP for my 5.3

[Botlfed]

4 hour cam swap awww come on G

i just think its not necessary is all, that cam makes good power already, id look at other area that may need improvment, like free mods like wieght reduction

mine and your mods are almost identical, but you have P&P 706s and i got P&P 862s

my heads are still stock Broseph, and i already kicked Tyler's mom out the back so there is 200 plus #'s gone seriously there isnt much i can strip off. Bumper gone, spare gone, receiver gone, spare tire holder gone, cant think of much else to take out of it. I might buy Stunna's 4.8 and swap my 5.3 crank in it and boost my compression and have a fresh short block, then throw on some ported heads and better intake....

How much HP do you think i can squeeze out of the LIL 5.3? NNBS 90mm intake with edelbrock 90mm tb, ported 706 heads, bigger cam, current cam is a 224/230 581/588. I want to hit 12's on motor... other mods will be a 3600 stall circle d and 4.10 or 4.30 gears...

For a realitively heavy vehicle, I think you would be better off with the cam you have vs. a "bigger cam". Heck, you may even see a gain in e.t. going with a smaller cam?

One of the car magazines did a cam comparo with 7 cams (the stock one and 6 grinds from comp). The smallest cam from comp smoked all the others in AVERAGE Hp and Tq, except the biggest cam. The biggest cam had slightly higher average #s due to its very high peak #s. In the useable street engine RPM range, say 2500-6000, the smallest one shined.

I was blown away, but the article made a lasting impression in my mind.

Who are you trying to beat Mr. GreenMonster ? I think that you are at a stopping point on what you can get out of it N/A... spray or boost is the next step and the other added mods to make that happen is expensive... ask yourself how much do you want to spend

Not looking to beat any one person, some are willing to spend everything on their truck im not, just want a 12 sec truck even if its 12.99........
