10K that's crazy on a 421, just a testament to your building skills.

Went up to 9600 rpm chip and it just did touch it for a bit on one of the 3 hooks this weekend. It was a loose track.
I think the power is finally nosing over enough up there enough to just not pull it higher.

Thanks
Re: 421 cube pulling truck engine
Randy have you considered just selling you 421 and buying this? The cheaper fuel would offset the cost of the engine.

Re: 421 cube pulling truck engine
I was just trying to save randy some money on fuel (10+ dollars a gallon depending one where you get it). I'm sure the medical bills from dragging his knuckles around have to be getting expensive.GARY C wrote: ↑Fri Aug 03, 2018 11:32 amGood power for a street engine but I thought you were against soliciting?slo-svt wrote: ↑Fri Aug 03, 2018 10:40 am Randy have you considered just selling you 421 and buying this?

I will stay away from the personal attacks and let a mans work speak for itself, Randy builds good engines and he doesn't have to be my friend for me to give him credit on his work.slo-svt wrote: ↑Fri Aug 03, 2018 11:40 amI was just trying to save randy some money on fuel (10+ dollars a gallon depending one where you get it).

Re: 421 cube pulling truck engine
I'm shocked a "good" engine could turn 9,000+ rpms over and over pulling a sled or win a dyno competition like emc. Makes me wonder what defines a great engine...GARY C wrote: ↑Fri Aug 03, 2018 11:47 amI will stay away from the personal attacks and let a mans work speak for itself, Randy builds good engines and he doesn't have to be my friend for me to give him credit on his work.

Re: 421 cube pulling truck engine
I don't know, maybe a stock class 289 with a flat tappet cam turning near 8 in a road race car making over 1.4 ft lbs per cube but I rarely call any engine great because it's just a matter of time before someone builds one better.slo-svt wrote: ↑Fri Aug 03, 2018 12:10 pmI'm shocked a "good" engine could turn 9,000+ rpms over and over pulling a sled or win a dyno competition like emc.

What was so impressive about this engine you speak of? Did it run on 81 octane or something?

Re: 421 cube pulling truck engine
I don't know what fuel the class runs but if you can rework a stock SBF to make those kind of numbers your doing something right.slo-svt wrote: ↑Fri Aug 03, 2018 12:42 pm

One thing I learned years ago is to factor in the fuel needed for the combo your building or you will destroy a very expensive engine by trying to run substandard fuel or octane booster because you either didn't know what you were doing or were to cheap to buy the fuel needed for the combo.

Re: 421 cube pulling truck engine
Didn't have any IAMO pulls to go to this weekend, and I thought we were gonna have a weekend off, but due to my son's lack of self control,..... we went to a Northwest MO sanctioned pull in Grant City, MO. Short tow at least. LOL
Below is a couple videos of our pull.
Won first place by almost 10'
The second place truck has a BBC I did for him.
https://www.youtube.com/watch?v=U5PaJILL3a0
https://www.youtube.com/watch?v=FGrsuQWcFzc
Said he was gonna get after it at the starting line. Brought it up till the shift light was on (9000 rpm) before he brought the clutch in. Had it flickering the shift light on on the way down track.
Just 2 more IAMO pulls left this year. Not sure where else we'll pull.
Edit, not sure that link to the engine posted for sale would seem as mean tied to a sled. Bet that sled would seem a lot heavier with that engine in our pullin truck.

Sounds awesome, don't miss a lick.

Re: 421 cube pulling truck engine
Sounds really good. I would like to see the engine on your brother's dragster and get some numbers.
Congratulations on the wins.

Re: 421 cube pulling truck engine
Here's a video of the second place truck.
It's Boone's 469 cube BBC.
https://www.youtube.com/watch?v=JYkIJVv-lGc
He needed a higher gear. Had 8600 rev limit in it, and it was hittin it mid track. Not sure we should spin a steel valve 4" stroke BBC much higher.
