Dragweek 2019 build

My buddy and I are currently on the waiting list for Dragweek 2019. Seems my fat fingers can't type as fast as needed to get in the field which sold out in 4 minutes, lol. Anyway, I'm looking for some information from the group about things to do to the car to get the best et possible within reason. I haven't drag raced in 20 years and then it was a leaf spring car. We will be driving my '67 Chevelle and I will give a rundown of the car, engine, etc. We will be running Street Machine Eliminator class which is 10.0 and above with a bracket race on the last day to determine the overall winner. The car is all stock suspension car and the engine is a '74 motor home 454 with 115,000 miles on it. The trans is undecided as is the rear gear. I'm trying to break the 11.99 if at all possible. I intend to leave the bottom end as of the engine is and just do top end mods. I may have a set of Merlin oval ports in the works but that all.....so far. Our goal is just to finish but I don't want my bucket to be a pig either.



So.....with that said, what are some recommendations on this build? I will be adding some brand EFI I think but other than that, I'm open to your info. Dragweek is a bucket list thing for me and my buddy. Its close this year and we are going for it!! We are between 25 and 100 on the waiting list and to be honest, we are just going to show up on Sunday and see if we can get in.



Thanks!!

Re: Dragweek 2019 build

A few friends of mine have done it. One of them ran the 10.0 class and a few others ran the 8.50 class. Biggest problem was driving from track to track. That's when stupid things would break and leave them on the side of the road. I want to run the 8.50 class. In preparation I'll probably do a smaller version by driving my car to and from The tracks in California where I live. Good luck.

Re: Dragweek 2019 build

I have an old rv 454 in my car that I put summit/crane 282H08 hft cam kit, competition products springs to match cam, 063 heads (brought comp up about a full point) with comp. prod. SS 2.19 int. & 1.88 exh. valves, eddy ag intake & 750 holley & summit 1 3/4" headers and the engine is a blast, pretty darn quick, I think the Merlin heads will probably flow better than PP heads but might be bigger chambers, does yours have maybe 781 heads? they're good heads
mine also had dished pistons about 2"rnd X .050 deep? and steel shim head gaskets orig. I used .027 X 4.32 mls for P/V clearance & cut reliefs deeper & wider

The heads are 781s and unfortunately the Merlin head deal fell thru for me. No biggie. Have you ran your car to see what that comb will et? Thank you for all of your information!!!

Re: Dragweek 2019 build

Make sure your car is NHRA compliant. The last thing you need to do is show up and fail tech at one of the tracks. Rulebooks are cheap, I’d order one and read it.

Re: Dragweek 2019 build

COOL DEAL !

I dont think you'll be able to truly turn that time (11.99) with flat tops an no compression, imho. RV 454 and 781s will yield maybe 8.5:1. Maybe a blower!? Seriously, you'll never make the TQ required at 8.5:1 to run an 11.99. 12's , sure. If someone can demonstrate me wrong, I'm all for it, but....

Why EFI? A carb is more foolproof. EFI dont make the car faster or more reliable. Contrary in fact. A Holley and two spare needle/seat is about as bulletproof as it gets. Again my opinion, so fwiw....

Again COOL DEAL! It will be fun!

PS I may have to think of this myself. Too bad its a clutch car!

Genes right I would be surprised with a full weight car if you would see 12.50`s probably low 13`s . I had a 427 in my car for years and my first version had small dome pistons with 215 heads that netted around 9.5:1 and with a 456 gear and 400 with 3000ish converter and a small solid roller [email protected] 644 on a 110 that ran 12.50`s down to 12.0`s with a lot of tuning. That same motor with more compression better heads and more cam and converter and suspension work ran 10.70`s. It usually takes some seat time and a lot of tuning to see the true potential of any combo, the gear would be another concern, to drive the car you wont be able to run a ton of gear which will hurt the track times. It sounds like fun I would change your expectations to high 12`s low 13`s and have fun.

Re: Dragweek 2019 build

Thanks for all the AWESOME information guys!!! I don't have the car together yet to get an idea of et and I'm honestly expecting low 13s/high 12s. I'm a N/A guy so I don't really want to run any kind of power adder but at Dragweek, that would also put me in the BigBlock Power Adder class. Some of those guys are running in the 7s. My bucket would be the slowest turd there, HA! My buddy and I just want to finish the event not on a hook but like I said earlier, I'd like for the car to et as low as possible.



Kirk - Thank you very much for your car details!!


Steve - Thats a great idea!! My bucket is so slow, I never even thought of that!!


427L88 - With the money a new carb is going for, I figured one of the efi setups for similar dollars would be the way to go. An 850 Holley is around $700-900 at Summit. A few bucks more and I can get into efi. I'm not dead set on it though......


B433 - Thanks for the info!! I'm probably dreaming at 11.99 but I'm dreaming big, HA!



Thanks again everyone!!!

I know a couple of guys that towed from California to wherever they ran dragweek last year or the year before, it broke the first day. They are a couple of idiots. I’ve known them for years, their stuff has never run right and they half assed the entire car. The one smart thing they did was bring the car out for a handful of Wednesday nights prior to leaving, it had to leave on a trailer each time, yet they still decided to make the trip, go figure.

Get your car done early and put some miles in it, including some track time. Then enjoy yourself.

Steve, that's the plan as of now. I'm buying parts as $$$ allows for now and I hope to have the car up and driving by June. Its gonna be ugly and crusty around the edges but It (I hope) will be reliable. The 1 st track is Virginia Motorsports Park in Dinwiddie, VA. and I hope to not trailer at all and just drive the car there and then start racing.
