5.3l vs 6.0l nitrous mustang build
which motor will make more power on a 150-200 shot and last. the goal is 9's in a 2700# foxbody on slicks not opposed to having some mild head work done to either motor. just looking for best bottom end, LQ4,LQ9,or LM7 i have everything ready to go except the longblock. car is bieng built for a grudge race because someone wants to argue with me that old school chevy motors make more power dollar for dollar so i wanna take a pretty much stock motor and kill him lol.

is a 200 shot unheard of of stock heads and bottom end, cam only?? i wanna get some usefulness out of it but im looking for the cheapest way to get the most power for a drag only setup..
soo lq9 w. truck intake
polluter cam or ms3
and a 150-200 wet shot...
what i really need is something i can spray enough with just a cam and get 550-600 wheel power i think its doable considering the cam puts down around 420 on bolton LS1's and an lq9 has more displacement as well as better flowing heads, and with the 200 shot it should get me there... what do you guys think

You should be just fine spraying 200. LQ9 is the best for sure but like already said gotta watch the extra compression. Often a speced cam for your aplication is going to be better then something off the shelf. Both of those cams are common and should work good but someone who knows cams might be able to get you more power for the same or less money.

I think you can get there with either engine. The car is light so it will 60ft hard if you hit it out the hole. I haven't seen anybody use the polluter cam but it can't be any worse than a MS3 or 4. If you have it already then use it, if you don't I recommend to use an MS3.

soooo rebuilt boneyard lq9,hellfire rings, ms3 cam w/ springs and roller rockers,stock 317 heads, 200 shot w/ plate, 40# injectors, twin 340 fuel pumps in tank, th350 w/ transbrake, truck intake, ported TB, longtubes, no power steering and a weight of 2700-2900 should get me there i hope.. i may go 4.56 gears and a spool also on slicks and skinnies. ive heard of people running all the way up to a 300 shot on stock motors so if i need to go 250 shot then i will after all it is a cheap junkyard motor..

You will mostly only need a 200 shot. Getting it out of the hole is the key.

ok well i got a set of 3.73's on the shelf at the shop i may use.. was either gonna run a 295 drag radial or the biggest wrinkle wall slick i can tuck.. part of the requirements for the grudge race is that we have to each drive out cars to the track which is like an hour and a half away.. so thats why i was thinkin drag radials. but if a slick can take the ride ill go that route... should i just run a WOT switch so it just hits wide open right out of the hole?? or is a 200 shot too much off the line.

Now if you were building an LS 427 to make the stakes even then he would be the one with the issue.

not sure we r both being secretive on the setups, to be safe should i grab some L92's ported with stainless valves, an l92 intake, and a 92mm TB? would that gain alotta power over the truck intake and 317;s?
specs on the L92's are
Intake Valve- 2.180
Exhaust valve- 1.60
250cc intake port
80cc exhaust port
68cc chamber
going from 72cc chamber to 68cc will net a small compression increase but who cares.. just wondering how well l92's flow nitrous
edit: i also am loving the new holly intake. may make a nice addition vs the ls3 intake seems to flow very well from what ive read..
soo new setup im thinkin
stock lq9 bottom end w/ hellfire rings
ported l92's
holley modular intake w/ fuel rails
FAST 102mm throttle body
1 7/8 longtubes
200 wet shot plate kit
th350 w/ transbrake
3.73 or 3.55 rear gears

275/60/15 hoosier drag radials man....trust me they will hook.They hook hard as slicks do but are a little more stable on the street.They arent street legal but i drive my foxbody 13 miles to the track on them no problem.Mine are on a 15x10x6.5 weld wheels.You'll have do some beating on the inner fender wells but they'll fit.
