ok sure you've all heard this but i gotta ask too what motor should i use in my 04 ext 4wd silverado. ok i plan on front striaght axle conversion 8" lift 36" tire 5.12 gears so on so i would like to have some nice low end torque but i want some high hp # i was think slp 402 any thoughts ?? right now it has a 4.8. i would like to take it to the track everyonce in a while for fun too. matter of fact there is a big jacked up ford desiel i would like to smoke. i seen him beat a old school 1500 pickup that was also jack way up. so i'd like to be the big silverado that gets to hand his *** to him. i'll probably have a stall and all that good stuff too nut would like to have good low end grunt for climbing through the mud and hills and just pure off road fun. thanks for any opinions just so much out there can't make up my mind.

oh and the 36" tires are just for daily driving i'm sure i'll have bigger ones for playing in.

 

I think the 402 would be a nice choice. And please be sure to get us some pics of this thing once it's done

 

oh i will it wont be soon by no means but i'm studing doing my home work all that good stuff so i can get the right stuff first. offroadunlimited said there goal is to have the front striaght axle conversion by the first of next year. got my fingers crossed.

its already out for 1500hd and above.

 

or an APE 408, really what kind of $$ are you tlaking about spending on just the engine?

 

what ever it takes to make a good strong eng but cheap at same time like i want to use my heads intake you get the idea i want to use all my bolt on stuff just need a good short block eng to put it all on. couse later on i can always put on other heads or get mine done and such.

 

well you have 5.3 liter heads and they will not breath and don't evven know if they will perform on a 408. I would look at a complete long block off of ebay or soemthing for like $2000 and throw in a cam, springs, arp bolts and jsut a few things to beef it up and you shouldn't have any probelms and you will get a ton more power. Or jsut get the 6.0 and throw a radix on it. I would give a call to APE about putting something together for you and you getting an idea of $.

 

yeah i was just hoping with a good p/p and valves would make it breathe good enough

 

really I think I would go with a 408 that has 6.0 heads and keep the compression about 10.1.

 

where can i find some info on this 408 from ape i went to the web site but found only like 427 but no prices.
