Two problems I see are,1- The 5 speed is too weak
2- The 1-2 shift will happen very quickly, the first gear ratio is too low. But I guess you can start off in 2nd  SteveW

I agree with all of what Steve said. Another option on the top half of the engine would be AFR 205 heads along with Edelbrock Super Victor intake. I have seen good results from them on the larger cube small block strokers.It would also need at least 1 3/4" headers. ------------------

Sweat engine though, I'd love to see pics. SteveW

Are we talking about Hot Street "heads up" racing or are we talking about a bad ass street eninge?
Yeah, Steve. I know you have a "bad ass" engine. ------------------

Ben/James/654212spd,I guess two89w will have to tell us how hot of an engine he wants. Anywhere from a 400hp stump puller to a 650hp monster. It's up to him, but eiher way the 5 speed isn't a good match. IMHO anyway the 408 will be a torque monster. When we switched from the 351w to a 408w was the same time that we decided to switch to a c-4. We ran the c-4 behind the 351w while waiting for the 408w to be finished and it ran considerably quicker in the 1/4. But the question at hand is, what would be a good "hot street408w". The engine in Melissa's '66 with a little less compression would be a killer "hot street 408w" it's not a bad "reliable bracket motor" either, even with more comression. And James' suggestion of the AFR 205 heads is a good one too. Although I like Vic Jr. He's a nice man  SteveW

1st thing ,this engine/trans is not for 1/4 mile(maybe the odd one here or there) given that,I think my tremec will be fine for circuit and street
How hot? current 347 with a tad over 400hp
well 408.....maybe 500!oh and the extra torque for pulling out of corners in third/forth would be nice
10.1 is about our limit on pump gas so i have to stick with that......does this help?

Looks like you guys are getting squared away on what Steve wants, but I just wanted to comment about the heads up Hot Street class. I'm not up on the NMRA's rules, but in the current scheme of things those boys in NMCA hot street are getting around 800hp NA out of 400 cu in! One guy I talked to a couple of years ago claimed he was running about .030" to .040" of piston to valve clearance. These motors are state of the art Competition Eliminator hi-buck!

Yeah, but that's not what two89w is looking for. BTW, you need 100 posts before the webmaster will post your pics. 
So start posting! Go to Sam's Place and post whatever you're thinking. There's also the men's room.... SteveW

Here is a hot street engine. Since your already at 408 cid.... drop in a 385 series motor, good comp cams hydraulic bump stick, some flat tops, DOOE heads mildly ported, a VCTR JR intake, some headers and your there. 500 HP easy from a big block. Hey if more cubes wouldn't help then why punch the 351w out?

Jerry, 'cause a 385 series big block wont fit in a '65/'66 Mustang unless you butcher the front end. SteveW

I wouldn't exactly call a custom A arm or strut/ tube front end "butchered"
