Nice man congrats! Didn't see it, what's the full build sheet? Any videos?

Fuel should be good I think: Cobra tank, pumps, 39 lb injectors. Tuner said the pumps were at 80% duty cycle. Could be compression. Previous owner told me it should be 10:1, but its definitely possible he was wrong and it could be lower (he was working on a twin turbo build). Not sure how much more I could get out of it with more compression though. Maybe a better set of cams would help? They're 106200s.

Edit: sorry, no videos. This was my first time at a dyno tune so I was just chilling seeing how they do things and oogling the cars that were in the shop.

The build as far as I know is:

Fully forged 5.0 stroker
Manley Flat Top Pistons
Ported Long Runner Intake
Intake Spacer
Comp Cam 106200 XE270AH-114 Cams - along with supporting springs, etc
MMR Stage 3 Heads
ATI Super Damper
39 lb injectors
Spec Stage 2+ clutch
Terminator fuel tank and dual cobra pumps
Meziere Electric Water Pump
MMR 7 QT Oil Pan
MAC LT headers
Lethal Performance Catted x-pipe
Steeda Catback
90mm MAF
JLT RAI

This is what the previous owner told me and was generally verified by the build sheet and the tuner (the tuner that dyno'd my car also built his motor but it was in 2008).

:uMad you dont have to be a douche and rage over another members dhno numbers. you don't/didn't know any of the specifics of his build except the fact that its a stroker motor with heads/cams (not knowing which or the c/r at the time when you posted) and Bolton's. Your saying just off those facts it has to be mid to high 400's in the 105+° heat.

As to f8l, iroush is around 13:1 c/r with stage 3 or better heads/cams if I'm recalling correctly plus the rest of his build. I would expect higher numbers from the mach with similar mods

And if you pay attention to what and who I quoted, it fits with what I said

I know. I wasn't bashing, just adding more specifics as to what iroush has in his build for comparison. Guess I should have worded differently.

Op, I love your car, any pics of the underneath, engine and interior?

Thanks! No pics of underneath, hood, or interior. Trying to get the exterior wrapped up, then suspension, then restore the interior - it's not in bad shape but it could use some refreshing as far as carpets and seats go.

Engine bay looks like a typical Mach 1 engine bay since its all NA. Eventually I'll get crinkle ford blue powder coated valve covers but that's low on the list of priorities. Underside of the car needs some freshening up as well.

Have you considered silver crinkle coated valve covers with black accents? It would match your shells and be pretty unique. Just a thought. Are you planning to keep the stock mach 1 interior or upgrade to corbeau/race seats

What my research has shown me so far is that your 390-400 RWHP seems about right..maybe more with a little better tune....but you have all the right mods

UDPs would push it to that point.

Did you consult NA SVT on the degreeing of the new cams?

Base 4.6L with OEM cats 257
CAI (K&N Filter) 5 262
Base 4.6L with degreed cams 16 278
MARCH UDP + damper 15 293
Hi Flow Cats/Cat Delete 8 301
BAMA tune 15 316


LT/ML Headers 10 326

Cams 30 356
BAMA tune 7 363

PSRI 10” + 90mm MAF + 39# injector + Aviator FP
8 371/
BAMA tune 0 371/

5L Stroker short block 25 396

milling the head intake valves will get you more I'd guess...and capitalize on the intake/injectors more...not sure about the MMR stage3 heads..

I was finally able to take my car into HPP Racing and strap it to a dyno to see with my own eyes what kind of power its making. This is N/A on 93 octane and the dyno was reading 109 degrees fahrenheit.

This is the car (in case you haven't seen :D)

Mother of god lol in my opinion you have the best looking new edge i have seen. Congrats on the numbers. I would be happy in the high 300s N/A bet that thing is a beast.

What research is that? I'd love to see the source. If stock heads a b head can ported intake and LT put 370 down ported heads and a full set of cams should be well into the 400's.

Is the car clean. Hell yeah. Is the power below what it should be. Yup. Just hate seeing great combos trip like a one legged whore in heels

Im pretty sure if the original owner was planning to boost it then compression might be lower than originally thought, those numbers are still damn impressive to me at least! and best of all the OP didn't have to spend a dime on the build! I wish my Mach would have come with a built motor.

probably 350ish...

NASVT posts mainly and dynos from other forums here and there across the net.

360-370 RWHP is possible without cracking open the engine and going comp cams that don't require new springs. C-heads
But you need the accompanying mods listed to go along with it....maybe $3000 when all is said and done..doing your own work.
$1300 for 320 RWHP and your very own cam degree kit..$400 for LT pacesetters (and prep for cams to open the exhaust side up a bit)..then $1300 for cams that use oem springs (106060. 106100..)....there may be some other mushrooming $$.

My cobra dynos at whopping 262 RWHP with a K&N..my cams are in need of degreeing to a proper TDC in order to make the advertised 320 flywheel..supposedly this RWHP is about right for the 1999.

do a search..porting heads doesn't help much..opening milling the valve seats help...c-head intake it think...

I'll search the HP list for a 400HP mustang with ONLY the mods you list (no UDPs, etc., etc.) in the the HP thread at Corral...I'd be interested in seeing it.

what RPM are you running at?

I'm not trying to make trouble or argue for the sake of arguing...but I have researched.

Q: OP,,,What kind of dyno was used??
and are these SAE adjusted numbers or standard HP numbers??

Also comp cams suggested degreeing of their own cams are not always the optimum..that's why I mentioned PMing NASVT...he posts on almost every forum and is usually glad to help...just degreeing per NASVT might pop you up considerably..IDK for sure myself though..
