hpfiend Posted June 16, 2016 Author Report Share Posted June 16, 2016 What's your budget? Since I can buy a 480 HP LS3 with zero miles crate for just under 7K I would think considerably less than that for a junkyard piece together mill Quote Link to comment Share on other sites More sharing options...

hpfiend Posted June 16, 2016 Author Report Share Posted June 16, 2016 thats a good guess- that engine did have a unique manifold with dual carbs.. maybe the manifold had individual butterflies Quote Link to comment Share on other sites More sharing options...

Littleguy Posted June 16, 2016 Report Share Posted June 16, 2016 Individual throttle bodies, so your intake manifold will be 2 feet high, lol. Quote Link to comment Share on other sites More sharing options...

Pick your battles. Yep. Also, consider all of the supporting mods you'll need to run that type of power. If you're even mildly considering a power adder, you can do a junkyard 5.3 and piece together a turbo kit plus have plenty of money for your supporting mods for under $7k no problem and make a reliable (if done correctly) 600whp.

Dafunk13 Posted June 16, 2016 Report Share Posted June 16, 2016 The couple guys I know with 500+whp both told me if they could do it again they'd just go F/I. You're talking knarly cam, deep sea compression and spinning it hard. Or you could just bolt on a blower and have WAY better street manners.

aussiek2000 Posted June 16, 2016 Report Share Posted June 16, 2016 Thanks for your post! 6L80 or 4L80? Tim on here? Did you port your tb and manifold? 6l80 with an FTI 3600 billet triple disk. Tim Toops, he is on here. Think his username is NHRATA. Futral Motorsports in Louisiana did my intake and TB. Quote Link to comment Share on other sites More sharing options...
hpfiend Posted June 16, 2016 Author Report Share Posted June 16, 2016 What do you all think of a 4.8 crank, 6.0 block, L92 heads, pac1218 springs, some turbo cam, ls6/ls3 manifold 80 lb injectors, and my gt45 turbo Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

If I could redo my Camaro over again I'd either boost it or spray it to the moon and call it done. If I would have done either of those, I'd still probably be driving it instead of getting frustrated and selling it off. Quote Link to comment Share on other sites More sharing options...
aussiek2000 Posted June 16, 2016 Report Share Posted June 16, 2016 (edited) If I could redo my Camaro over again I'd either boost it or spray it to the moon and call it done. If I would have done either of those, I'd still probably be driving it instead of getting frustrated and selling it off. If I did it again, I'd go cam only and none of the extra crap. Throw an LSA blower on it and call it a day. I've got as much in headers and head work as a used blower costs.

gillbot Posted June 16, 2016 Report Share Posted June 16, 2016 I did cam, headers and such but my cam was pretty aggressive. After that I started chasing NA power and realized it was too steep of a hill to climb. I had too much into it to go back but if I could have started over, it would have been boosted.

caseyctsv Posted June 16, 2016 Report Share Posted June 16, 2016 Agree on "if I had it to do all over again I would go F/I". I am only at 475 RWHP but the big cam is just too much to drive every day. Quote Link to comment Share on other sites More sharing options...

It can be done, but it gets expensive. N/A engines are less forgiving to mistakes and non efficient parts than forced induction engines.

Linn1647545492 Posted June 17, 2016 Report Share Posted June 17, 2016 I've made over 500rwhp N/A since 2006 with, what is now outdated technology. It's not hard with the new ls3/ls7 heads, intake, and cam options that are out there to make 550-600 you just have to be willing to spend the money. For the money go F/I.

caseyctsv Posted June 17, 2016 Report Share Posted June 17, 2016 500 N/A is pretty common these days...550-600 is not. You start getting $$ for those other 50-100 RWHP Quote Link to comment Share on other sites More sharing options...
