Hey guys,

My name is Tim, 26 years old, and I am from the sunny state of California. I'm new to the classic muscle car scene, but am ready to learn as much as I can!
Anyways, here is a quick intro to my 1970 Mustang Fastback. She is from Indiana and a joy to drive so far. I hope to meet some of you as the build unfolds :)

By the way, what do you estimate she's making HP & TQ wise? The previous owner told me he did a few dyno tests. Car dyno test (approx. 500rwhp) & engine dyno (over 500hp).
However, I'm always a little skeptical. I plan to get her tested myself, but any input would be great! Please see the build list below for details.

Nice looking car, I would guess that it is closer to 450 HP. What compression & what cam?

I updated the build list, it was missing a few pieces. I'm don't know what compression and a Comp Cams camshaft is installed, don't have the part number.

Without knowing cam specs, hard to make any good guess.

Looking at the pics, I see what appears to be factory cast iron heads. Even with “milled heads” definitely not 500 wheel hp. For wheel hp, I’d say more like 300 hp (or about 350 flywheel hp). And that’s being optimistic.

Not to say that it’s impossible for a 347 to make 500 hp at the flywheel, but it takes quite a bit. Maybe there are more details not provided, but just from looks and given specs (or lack there of), not likely. Keep in mind, engine has to be putting down nearly 600hp to make 500hp at the wheels (assuming 15%ish drive train loss).

Still, car looks great. Not trying to be a downer, just a realistic. Now, if it does put that kind of power, i would want to know ALL the specs, because thats the ultimate sleeper engine.

Don’t forget to post results when you get her to the dyno!

No worries man, I appreciate the honesty. I am skeptical about it myself, but he said it again when I asked again for more details. I was able to call the shop that did the rebuild, see attached. Hope this helps.

It looks like 10-1 pistons, extreme energy cam. Nice setup, however it will only probably be good for only 400 HP at flywheel. You can still run low 13 sec. quarter miles with it, nothing wrong with that. Its a sharp car!

So, decently sized hyd flat tappet.. any info in the heads? The build sheet was totally blank in that area. Heads have a huge part in power production, and factory windsor heads aren’t exactly tops when it comes to performance.

I’m not trying to bust your chops man. Honestly, just get it on a dyno. Way better than anybody can say about power/tq you engine is making. I just really think the PO was blowing smoke up your fourth point of contact. At least it sounds like it.

Overall it still seems like you have a fun engine.

Someone did mention the highway gears in the rear end.. puts some 3.50s or 3.73s, and you’ll be cooking!

Nice looking car! I think Red on these cars is always attractive! Like everyone else said, get it on a Dyno. That way too, you can get it dialed in for the best performance. Have fun with that sweet looking ride!

Mines a 69 351w stroked to 414ci. Holly 750HP, CompCam 280H, 10.75:1 compression, JBA Shorties. I did a bit of porting on my cast heads. :) I'm hoping for 425hp at the wheel and had a chassis dyno session set up for when I was at the PITS event in Tn last month, but that has now been postponed to July. Will keep you all updated.

Thanks for all the feedback and compliments guys! I will get her on the dyno and post the results when I get the chance. I believe in numbers myself, so I agree it's a good build but to merely state that it made 500 at the wheels and then a bit over 500 on an engine dyno without sheets to prove is not realistic to me. And to answer the question about the heads, I'm certain they are stock and have only been milled.

Welcome to VMF. Great car, can't wait for the dyno results. 500 RWHP sounds a lot, but you will have a lot of torque and this is that you feel :)
