Default Re: DP #24 Engine failure....

Rich Biebel;--6.1 Hemi.....= 374 cubes....What is the bore and stroke.....What is the main diameter and rod diameter....what is the rod length.....

4.055 3.580 370 8 6.200 12.6-1

Piston appears to be a Semi Hemi design...not a true Hemi.....

Correct

What is the cam lift......

385 370 .0135AB Dome .137 14.8cc 2100/1600 584/552 Beehive .039

What do the heads look like.....what is the intake and exahust port CC's and what do the heads flow.....port shapes? All this stuff says a lot about the usable rpm range of the engine.


They flow about 300in 200ex @600 on a stock SRT8 head....I dono the DP head but there is no port difference only valve size on in 2.100 instead of 2.08

Com cc about 79, dont recall ports at moment...

I can look some of this stuff up on the NHRA Engine blueprint guide specs.....but I thought you could tell me some of this stuff.....

Doug Duell and Irv Johns have run some 9.80's at what weight?

Not really sure, rumors only other than unsanctioned runs and weights but that was shared in confidence and I keep that above all else....

Well its above 3270 ship+driver and I believe we are the lightest by about 40-50 lbs of any of the DP's but....well...we spent a lot of time doing that , and things like 8.75 and 904 vd dana and protrans...

Just interested in knowing some of the particulars on one of these engines for comparison to others.......

374 cubes is pretty small to be running 9.80's at 132-133? I am guessing they are spinning them pretty hard to run those kinds of numbers....so my educated guesswork says lots of RPM might be normal for one of these.....

There isnt a DP person running I have heard of spinning one UNDER 8k in a run of competition.....maybe there are and if they want to speak up....hey....lol....but everyone I know is turning it that and FASTER !
