First of...is it a 408 or 409 ironblock??

Mainly..what kind of dyno numbers (HP/TQ) can a guy expect from a well built motor from Futral or some other big cube shops?

And definitely what kind of track times? I want to go 10's on motor at stock weight....HELP!!!

 

Look what Allan did with the 346 -516rwhp and all his engines make power. I would expect 500rwhp and close to that in tq with a 408.

 

4.030 bore x 4.000 stroke = 408

4.040 bore x 4.000 stroke = 409

I'm going to be building up a 408/409 block within the next year (I just got my block) with all the new parts coming out and with guys hitting 500 at the wheels, 525 RWHP/500TQ or more should be attainable.

It really comes down to how much you want to spend, I'm figuring to spend about $5,000 using the Eagle crank.......

Would not get hung up on dyno numbers. Many, including myself, have proven dyno numbers to be nothing but a tool for tuning.

I only make 400rwhp, but the car runs 11.0 @ 121 all day long. This is a stock crank and stock bore iron block. 10's with stock weight should be doable power-wise, but there are other parts to the equation. Remember, ET is all about launching. If you don't launch well, don't expect good ETs.

 

I know, you don't have to rub it in that I suck at launching my car....

 

Who do you guys like for making powerful, fast engines?

 

I built my motor myself and it puts down 450rwhp/tq on a Mustang Dyno. I'm beating friends on the street who run high 10s. Havn't made it to the track yet though to see what it can really run.

 

Do you think that this route would be the best performing engine under 10K. I do not want to spend the money on a super stroker or something over 420 ci.

 

yes iron block with Eagle/Diamond rotating is the way to go. Heads/cam/intake choice is critical as well.

~490-510RWHP and similar torque should be easily attainable.

 

Why the iron block? We have seen people do well with the aluminum, even with or without boost or juice.

Iron block is the cheaper way to go. Since you would have to re-sleeve the aluminum block.

true but if your making more power your car is capible of making better times.
My goal with this car on motor is 520+rwhp 500rwtq with dual cut outs after the headers and 700+ on spray.
Not sure if I will get there with my 408...409 pretty soon
but I am sure as hell gonna try!

 

If I did not do the 6.0L block...would you stay with the stock one...or go with a LS6 for the PCV reasons?

Aside from blocks...Iron is a stronger metal than aluminum right?

Also, could an aluminum block (without a doubt) handle nitrous as long, and as safely as iron??
