Re: Race Engine Build time.

Honestly, I switched over to 100LL from 110 race gas given it was around of $8 per gallon where I could find it at the pump and even crazier the few times I bought 5 gallon cans of VP at the track.  This was about five or six years ago so I imagine the price has gone north from there in our current market. That and as stated earlier, I was getting inconsistent ETs depending on where and who I bought it from, requiring constant fiddling with my previously-declared regrettable decision to run dual quads.

Yes, there’s tons of conflicting opinions on the Internet where of course everyone is an expert, so the decision was after careful consideration given all the time and money spent on my engine build.  If you remember from past posts, I started with the famous Don Dulmage Old Reliable recipe then went a bit off the reservation by going with a stroker rotating assembly purchased from Muscle Motors. (Ol’ Master Don himself rolled his eyes via email on this plan deviation.)

So far so good though. Zero knock events and consistent performance, supporting the positive opinions I’ve heard and read. One of the compelling arguments in favor of 100LL is that it has to be of a consistent quality as it is running in engines with zero tolerance for in-flight issues. I’m obviously not running the Fury 10,000 feet above Earth but that makes sense to me, nonetheless.

And I apologize if I offended anyone with my Chevy comments. I really shouldn’t reply on Friday evenings … the wife and reserve it for a cocktail or two after a long week’s work.  :-)

Thank you for the great information Jim!  So…after reading your reply on 100LL and the “myths” warning against using AVGAS in street vehicles your real-world experience it runs fine and the naysayers come from the Duntov 30/30 club! 😊

And you are really doing well at 12.1 compression with iron heads on approximately 103-104 pump gas octane rating.

Hi Gary!

 

Yes, the LL in 100LL stands for low lead, but that is a bit of a misnomer, as I understand it to be relative to the lead content of other aviation fuels.  The 103 octane statement is from some research … as I understand it the 100 in 100LL is not a typical octane rating, and I’ve seen a few test results posted where it is more like 103 or 104 octane.  There are also all sorts of threads out there debating the use of 100LL, as well as a bunch of myths, e.g., it is too “dry” to run in car engines, it is a “dirty” fuel, etc., but from what I can tell that’s noise coming from the likes who run “3/4 race cams” in “high-winding” 327 Chevys but also likely haven’t been rolled out into the sun in a few decades.  😝

 

Thank you,

 

Jim

Hi Jim & Don,

Interesting thread on airport fuel and 100LL at about 103 octane.  What does the LL stand for, “low lead?”  Are you running aluminum heads with your 12 to 1 compression?

Thank you!

Question out of curiosity … does your nostalgia class allow roller cams?

Engine builder is tossing out 11-1. Depends on what's on the shelf these days given supply chain issues.  I always thought a REAL race car ran 12.5 to 1 but I'm not out to beat the heck out of my stuff so if I can get into the 10's comfortably at 11, great. 

 

I mistyped, also. 4150 carbs is what we're allowed with Holley based units. Have an AED 850 DP on the shelf but not sure that's enough with 500 cu in and 700 lift cam. Will say the, 95% of the NSS racers run dual quads and I can get all the help I need to make it work -friendly group.

Hi Don,

 

It was a typo.  My apologies.  I meant to say 110 octane might be an overkill for 11:1.  I’m at 12:1 and running 100 LL.

 

It depends on the airport but I’ve had really good luck. The first time in I go into the office and introduce myself and ask if it’s OK.  Two out of three locations I tried, the guy working there was super nice and ran me through the process of getting fuel.  All the places I go are small, rural airports.  One has a grass runway!

 

The pumps have all been pretty much the same. These airport manager fellas are analytical types by nature so act interested in the process!  The pumps are self-serve, right on the tarmac, and take credit cards.  There’s a ground strap that reels out, so just to show I’m down with their rules, I reel it out and clamp it to the trailer hitch of my truck. I bought a 14 gallon boat fuel can that lays horizontally in the bed of my truck and it works perfectly.

 

Here’s a link to an internet site I found to locate small airports.  You may know where yours is but this site will show if and what fuel services are available at each.

 

Take care,

 

Jim

I heard airport fuel was tough to buy. Do you need a good friend to obtain it?

 

Not sure I understand why 11.0 would be an overkill. Care to expand? Did I miss an important point in your narrative? 

 

I'm not really thrilled with the dual quad. There's some pretty good 1150 based single 4bbls. Just that's what the class would prefer you to run.

Hi Don,

 

Been down a similar road and here are a few things to ponder:

 

  • Race gas is quite inconsistent from one brand to another.  If you want consistency, stick with one source.  If you run Sunoco 110 on Wednesday and Torco 110 on Saturday, you will see different results
  • You might find 11:1 is overkill.  I run 100 LL from the local airport.  It’s actually about 103 octane, very consistent, and much, much cheaper.  If you can get access to a portable knock sensor you can setup your timing to be efficient and safe.  Our Mopar motors (like most motors) are what’s known as knock-limited.  This means your timing can only be advanced to a few degrees before knock and not to MBT timing
  • I also went with the CH-28 dual quad with Eddys as I wanted the nostalgia look, and it certainly yields the oohs and ahhs, but in retrospect I regret it from a competition standpoint.  Dialing in the carbs for weather and track conditions is an order of magnitude times easier with a purpose-built, single four barrel from someone like AED

 

Have fun!

 

Jim

I've finally decided I'm using race fuel. Extra $300 a year. Not confident that pump gas can be  consistent run to run and week to week.

You basically have what I am running.  Similar internals.  425 cu in.  Same carbs ons a crossram.  I stayed with 10 to 1 compression ratio to tolerate using pump gas.  It still diesels so I shut it off with the 727 in gear.  Bent a custom push rod once.  I add a few gallons of VP 109 octane.  It seems to like that.

 

Enjoy, but it aint cheap.

I've embarked on building a 600 HP+ ENGINE for my Belvedere. I'm not out to set low ET, just want a reliable unit capable of going into the 10's in a sub-3500# '65 Belvedere. 600 - 625 HP to allow me to dip into 10's. Been mid-30's with 525 HP +/_ and a bit more weight. 

 

So far, we've ordered the Trick Flow 240 heads (non-Max Wedge ports), have an in-Line Edelbrock CH-28 Dual Quad intake with 600 cfm carbs complete with linkage and fuel lines, 440 block. Ordered a high dollar Milodon pan, windage tray and external oil system. Suspension is in - all Calvert. Pulling back seat in A-990 fashion. 

 

Next step is 4.25 stroker with likely 11 - 1 compression - time will tell - race gas motor. Billet main caps. Solid Roller, about .700 lift,  with Harland Sharp rockers and stafts. 

 

Anyone with spare parts in thie unpurchased area, I'm interested.
