Dave, The engine is pretty mild mannered. It dynoed at 535 HP @ 7000 RPM, 400 Ft Lbs Torque. Peak torque of 463 FT Lbs @ 5900.
360 CI stock stroke, .060 over bore
12.9 CR
Filled block
Dart Pro II aluminum heads, ported, (no flow Numbers)
Comp Cam, custom grind, .682 Lift, 272 intake Duration, 280 Exhaust measured @ ,050. 108 lobe separation.
Hilborn 2.5" Stack injection
I don't have a temp gauge but the hotter it is the faster it runs.

1:76 trans gear, 5700 stall
I dynoed the engine and it starts to fall off around 7200. I am going through the lights @ 8200 and it is falling off before the lights. My thoughts were to get the rpm down closer to the max power curve. Does that make sense or am I not thinking correctly?

Nice looking car Dave!!
I have some more data from the race this weekend. I ran 5 times, the first 4 laps were 8.21 - 8.27 @ 161-162 MPH. 31" Hoosires, 9.25 ponds of air, 8200 RPM through the lights.
I went out in second round but was able to take one last test run so I put on my 33" Mickey Thompson tires. I went out 30 minutes after my last run , the track temp was 110 degrees both runs. 9 .25 pounds of air pressure. The fourth run I ran 8.244 @ 162.18, the fifth run with the M/T's I ran: 8.249 @ 161.63, 8100 through the lights. 60' time was .014 slower with the M/T's but they launched hard.
I learned a whole lot with all those runs. I am very happy the car is so consistent. I hope this isn't too much information but since I started the conversation and received a lot of great advice and information from all of you, I wanted to share what I found out.
I still need to pick up 2 tenths because we have a great 8.0 program here. So I am going to drop my gears from 4:57 to 4:11 to get the RPM in the correct power band of the engine and hopefully pic up a tiny bit there.

I had my first test and tune of this year last Wednesday. New convertor picked up1.5 tenths and 5 MPH. 8.20 @ 160 MPH. I I ran my Hossier 31". I started at 7.5 pounds and ended up @ 9 pounds for a cold track. Air temp was 62 degrees.
WE have our first nostalgia race at New England Dragway tomorrow. I hope to see some of you there??

Jon, Thank you for the great feedback! The 7800 Stall converter was a 7", I now have a 9.25" converter that was recommended to me. The fellow who does the converters is in Texas, I am trying to get the name from my transmission guy.
What compound do you recommend for the Good Years? I also want o get another set of rims. I have a set of 10" Sander rims now but I want to have another set of mounted tires for back up. Where do you recommend I buy a set?
Oh I forgot to mention like you pointed out Jon, The MT's are very heavy compared to my Hoosiers!!

Hi Dave, nice to talk with someone else with a Worm Chassis! I only put 6 runs on the tires but each launch I felt as it shifted ever so much to the side. I played with tire pressure from 7-8 pounds but no difference. My first run the track was cool and at the 1000' foot mark i felt the tires break loose as the the car started to walk to the side and for the first time I had to drive the car back to the center. My times were very close to my Hoosiers 31 x 10.5. The Hoosiers launched and drove just as straight as a die. The only reason I went to the 33's was to to raise my gear ratio which it did.
The highest RPM i have left so far is 4000 Rpm. I finished the car last September and was only able to get 10 runs on it so I wasn't trying to push it hard. My wheelie bar height is 2", My Hoosier tires, CO7 ran the best with 7.75 pounds air pressure.
THe engine is a 366, 13:1 compression. .680" valve lift, ported Dart Pro II heads, filled block. The engine dynoed at 535 Hp at 7000 Rpm and there was more left but I didn't want to push it too hard. All my runs I made I had the engine tuned according to my dyno data around 485 HP so there is quite a bit left.
Right now all I want is seat time. I plan to rent the track in a few weeks to do a bunch of testing.
I sent my converter out to be checked and what I was sold was a 5600 RPM stall but what I actually had was a 7800 RPM stall converter. Needless to say that should change things up a bit!!
Call me on my Cell anytime if you want to talk and let me know if I can help any other way.

I love my 11 pound Braile battery. I run 13:1 compression and I can crank all I want all day with no drop in voltage. I run a magneto and no electronics so I can get away with it just fine.

Thank you for the compliments and information.
Luke,
I had a friend of mine take pictures for me and I love the effects of this one. I hope to hit all the nostalgia shows at New England Dragway and if all goes well I would like to get over to Lebanon Valley at least once to support them as well. Also June 20th there is an old time drag race (330'), flag start 1972 and earlier cars and dragsters at Sterling Airport, Sterling, Mass. Should be a lot of fun!!
Bill,
I first ran 31 x 10.5 Hoosiers that I loved but I was twisting the engine too high so I went an bought a set of Mickey Thompsons 33 x 10.5 which brought my gear down but I did not like the way they handled on the track and especially on the launch. My thought now is to stick with the 31's, and raise the gear. I like the idea of as small a tire that works well. Everyone I have spoken with has recommended going to GoodYear but They do not seem to have the narrower tire so I would have to go to a 12" wide tire. I have a friend who has a set of GoodYears and I think I will be able to try them at my next test session. It is really good to know that Jon has a stockpile of these tires!!
I look forward to meeting you Bill and anyone else up here in the NE!!

Front Engine Dragsters / Rear Tire selection
« on: April 09, 2015, 04:21:34 PM »
I am running a 180", 1300#, 360CI small block on alcohol. Rear gear is 4.57, Glide, Engine dynos @ 540HP. I want to run a 31" Good Year tire but all I can find is a 12" wide tire. Right now i am running a 10.5 wide tire.
I have to buy a set of rims so I have a spare set of tires but I wanted to find out from you folks if you thought a 12" was too much meat.
Any thoughts would be greatly appreciated.

I,m getting on the kerosene queen Thursday and will be there for Friday through Sunday. I went in March and met some great people that I want to show pictures of my car to now that it is finished and I have 10 runs on it.
My daughter will be helping out in the TMS Titanium / Crower / Lucas Oil booth for the weekend.
I hope I can meet some of you folks as well!!

Thank you all for your input. I have the axle set up now for 15 degrees and we will see how that works on the shake-down runs. I am sure it will be just fine!

Front Engine Dragsters / Front End Caster on a FED
« on: August 15, 2014, 09:52:36 AM »
I have been trying to find out what a good starting point for caster angle for a 180" FED. SBC, injected alcohol, Projected mid 8's 155 MPH.
I was told that a good rule of thumb was, 1degree of caster per 10 MPH of top end speed and I just wanted to back up that information. I have seen so many front ends at wide varying degrees of caster and cannot seem to find a consistent consensus.
I plan to dyno the engine next week, the roller is all done so I should be running mid to late September.

Thank you all again for the great feedback. What a breath of fresh air having this resource from all angles. I don't feel so alone doing this project!
I'm off to Bakersfield next week. I hope to see a lot of rigs and get more ideas.
