if a stroker LT1 doesnt make 430-440rwhp with a ported stock intake, heads and cam something is really wrong. i dont know why its so hard to believe. thats right in the ball park will several of my friends 383s-396s.

 

Thank You!

It's been a while comming and my turn for a change...... that's all. I'm also one of those whom bit on Agostino's lies and it took a while to correct his screw ups. The heads were orgionally done by ARE....... but we won't go there with dyno posts on that one.

 

I think Vettes might dyno a lil better than an F body but the #'s are where they are because Denny focuses on EVERY detail, has EVERY bolt on/mod and spent the time to "hands on" tuen the car in search of more power.

We were kinda disapointed in the early #'s (414 RWHP) and had hoped for about 10-15 more HP. With the 114 LSA cam and 561 LT1 castings with 2.00 valves, that might be all we could ask for with 385 cubes until he found out the rings had not seated. A few more miles of driviung and the rings decided to seal off a lil better and resulted in some descent #'s.

I will post the dyno graph for everyone to see. The TQ curve is impressive as well.

anyone wanna host this graph?

let me know?

I can host it. Send it to ahotvent@aol.com and I'll put it up on my website when I get home from the office in 45 min.

 

That's a bold statement considering the company you're in. You might want to qualify and revise that statement. Lots of strokers out there that don't make 430-440rwhp, and there's nothing wrong with them.

Denny's combo is believable, and he's been at it (trial and error) a long time. Congrats on the awesome numbers, Denny.

 

The results speak to your work as well, Llloyd. Congratulations.

if they arent making it they arent making as much as possible.

 

tireburnin,

graph was sent.


SS MPSTR,

thanks for the props. I am learning more and more all of the time. Some people have thing all figured out and no desire to learn anymore. I am not in that catagory. I find more things every few month or so that help me create a better cylinder head.

I have seen a post recently that stated that "400 RWHP is not a given" if you have ported heads, 230 + duration cam and bolt ons. That is VERY true and the strokers do not seem to dyno much better even though they have another 31 to 46 cubes. When you are dealing with GM LT1 castings (not LT4, TFS, AFR, etc) the peak HP #'s usually do not seem ANY better. More area under the curve and more TQ everywhere but the peak #'s do not seem any better usually.

All in all, a 420 RWHP stroker is nice to see.

ive seen a 95 m6 Z go from running 11.80s@117 w/ a H/C pkg that was making 405rwhp. then changed the shortblocks (to a 396) and used the same cam and ported intake that was on the 350 and made 437rwhp, but ran 11.30s@123. its area under the curve

 

great numbers Deny! i know my rings took a while to seat as well!!! just wondering what rings you are running? if you don't mind divulging. or pm if you'd like!

thanks

I see what you mean SS, i've been lurking around on the boards for years and seeing the MANY different combos that have been run across through the years makes me stick to certain views. There's a correlation that i've drawn also, and anyone is free to agree/disagree on this. IMO, i tend to agree with 93turbo5oh on this point. A 383/396 with LT1 heads from a "well-known" or "reputable" porter SHOULD be making ~430-440rwhp. Not heads ported by some "speed shop" down on 5th and main or "my buddies' buddies' best friend's professional engine builder". It's almost like clockwork when i see someone build a 383/396 LT1 with ported LT1 heads from certain vendors... like in this case i see denny's car with the certain parties involved and look at his power... when he first started this project i pretty much expected what his results are now. A year or so ago i remember someone else having a 383 built by BRE and making around 430-440rwhp. Then a handful of others just like these making the same power with about the same specs. The people behind the building, porting, tuning, etc really pay a huge part and when those people are involved in similar builds you can expect similar results. This is why i also believe that a 383/396 SHOULD be making power in that range with similar mods. It's apparent that these people know what to do to make the most of this combination (383/396/ported LT1 heads/HR cam/excellent tuning etc etc...). Just my view on it.

 

Damn it. now I really cant wait to get my stuff back from Lloyd. The more I hear about Lloyd the better I feel about my new setup. Especially if you are able to get that out of LT1 castings with a 2.0 valve. Im really anxious to see what a set of LT4's will do for my stroker.

 

Here is the dyno graph that Lloyd sent me. Congrats again...looks like a boat load of torque.

 

Why do the hp and tq both take nose dives?
