Hey all, Been missing my mustang like crazy.. had a 69 coupe (Followed by a 99 gt convertible for a short while). Forged 331 and a built c4. Dynoed 380whp/11.7 @ 122. Car handled like poop but she did scoot. Moved into a more modern platform; Mazdaspeed 3 and Mazdaspeed6. Built up the...

Alright guys... I'm lost. At the moment I have a built forged 331 with 10.5 compression procomp 190cc heads etc... Attached to a built c4 and shift kit. It's in a 69 coupe and puts out probably over 400 crank horse. Now I'm in a dilemma, I can sell off both the trans and engine for 6000 to my...

Based off of other's builds, about 450whp. Haven't gotten it on the dyno, but it scares the sh** out of people on the freeway hahahaha. And ya i'm worried about splitting the block, but honestly if I do, I'll end up building a N/A 460 and be done with it

Thanks for the replies guys! I've decided that im going to boost my 331 stroker, given that there is a much bigger aftermarket for the 302s... I wanna run boost because my daily is a 1999 saab 9-3 with a holset hx35, and im ADDICTED to boost. It's gotten to the point that I drive the daily for...

Hey guys, looking to build a big block soon. I got a 331 with a built c4 in it at the moment and getting kinda bored ;) So here's a few questions... 1). Are there any 460 turbo manifolds on the market? And if not I understand you can flip some truck manifolds, but will those fit in the bay...

Just about to FINALLY build up my C4 Its going into a 69 coupe, behind a 331 making around 400ish hp, this car isn't a dedicated drag/race car, just something i'll be bringing out to the 1/8th and maybe some autocross events. I'm going to be using broader performance's 500hp kit with a full...

Hey guys! I blew up my stock c4 in my 69' coupe during my last run at the strip :( I was going to rebuild it with broader's stuff but i kinda wanna do a t5 conversion so i have an overdrive gear and i wont have as much power loss through a manual trans. How durable are these trans? the motor is...

It's actually out of a 76 maverick

Will that kit be good enough? And does it have all the stuff I need? Also what about reverse clutches?

So after my first trip to the track I blew up my c4 :) Ive been having chronic problems with it since we hooked the 331 up too it, its a stock tranny with a shift kit and 3200 stall converter The engine is making over 400 hp and whenever I run it hard for a little the trans starts blowing oil...

So I got back and my best time was 8.4 @ 81.38 I only got 2 runs and this was my first time on the strip ever, the 60 ft was 1.889 so I didn't to bad with stock suspension and a ton of wheel hop but the only issue was on the 3rd run I blew the tranny... 3rd gear is gon, I was planning on...

well I was looking over my car before I headed over to irwindale and noticed that I have a lot of dent marks where my drive shaft meets the rear end. I checked to make sure all the Ubolts and driveshaft bolts were tight. Everything checked ok. I have noticed that in the past few days my upper...

What's a good valve body for a c4? I have a b and m transpack but I'm not to impressed

Oh ok thanks! And also how long will a stock c4 last with a 400 hp+ motor? Ive read only 350hp then I've seen 550hp, anyone know? My trans has a 3200 stall, external cooler, and band transpack

Hey iskwezm are you running a stock block or aftermarket? I read your build and I was looking into adding like 7 lbs to my motor because my compression is pretty high but I'm scared that my block will split

Well I'll be runnin it at Irwindale this Thursday I'll post what my times are, and also does anyone know a good budget suspension set up on a 69? I know caltracs are suppose to be good but I wanna do a 4 link just cause I think I might try to do a little auto cross for fun

Well thanks for all the help guys I'm going to try to bring it out to the track soon if I can find one here in southern California.. Does any one know a reputable dyno in the SoCal area?

The 600 has been tuned and the jets altered I also set up a metering block in the secondary with I think 78 jets in it and theyre dual springs I can't remember the strength it's been a while but I know the valve train is very stout

Is 750 too big? And what about a single plane victor intake? I have a dual plane I think weiland stealth? I'll check it later
