Dirttrack510 Posted April 1, 2012 Author Report Share Posted April 1, 2012 Yeah, they were pulling away, but just barely, if you listen carefullly in the video you can here the rocker starting to tick early in the race. I think it got out of adjustment and kept getting looser till the cam slapped it hard enough to bust it. I can't wait to see how it runs with the A87 closed chamber head. It should be just enough to make the car really competitive. (I hope) Quote Link to comment
Dirttrack510 Posted April 2, 2012 Author Report Share Posted April 2, 2012 I got the head swapped out last night, set the cam at 4* advanced. Tonight i'm gonna try to install the manifolds & start it up. Quote Link to comment
Dirttrack510 Posted April 3, 2012 Author Report Share Posted April 3, 2012 I thought i had a bigger cam, but as it turns out i'm running a .475 lift ISKY cam. I just read it on the end of the cam. Quote Link to comment
Dirttrack510 Posted April 3, 2012 Author Report Share Posted April 3, 2012 I got the header installed, just gotta finished up the intake and hook up all my hoses tonight & it should be ready to race again. Quote Link to comment
Dirttrack510 Posted April 3, 2012 Author Report Share Posted April 3, 2012 Yeah, i can't wait to get it back on the track. I'm really curious to see if there's much improvement with the A87 closed chamber head vs. the 210 head... Quote Link to comment
jun Posted April 4, 2012 Report Share Posted April 4, 2012 I too have a 210 head, and would be curious to know the power increase with the head swap! Quote Link to comment
Dirttrack510 Posted April 4, 2012 Author Report Share Posted April 4, 2012 My hope is that my 210 head was limiting the gains of my Edelbrock intake, weber carb, cam, and header... and that i'll pick up around 25 horsepower :hyper: , but I don't know how much more the A87 head will flow than the 210 head. I wish I had access to a dyno, does anyone have any idea if I'm thinking in the right ballpark for horsepower gains? :unsure: Quote Link to comment
Laecaon Posted April 4, 2012 Report Share Posted April 4, 2012 I too have a 210 head, and would be curious to know the power increase with the head swap! Jun, if you have a L16, keep the 210 head. By swapping even to a closed chamber you will drop compression. Quote Link to comment
Dirttrack510 Posted April 4, 2012 Author Report Share Posted April 4, 2012 Laceon, do you think i'm gonna loose power with the swap? Quote Link to comment
Laecaon Posted April 4, 2012 Report Share Posted April 4, 2012 Stock L16 block? Not really sure. If you must keep it a 1.6L get the L24 pistons (flat tops), but now you are in race season. You have some hop ups, and such, and you race in the higher rpms which the 210 just hurts flow there, so I would say in your case it would probably help...time will tell... Quote Link to comment
Dirttrack510 Posted April 4, 2012 Author Report Share Posted April 4, 2012 That was my thought since i'm rarely below 5000 rpm's. Quote Link to comment
bananahamuck Posted April 4, 2012 Report Share Posted April 4, 2012 yeah , but those looked like neons and an S10 which run a engine that is almost twice as big to start with. and the dodges are twin cams...Even though they are front wheel drive they should be able to pull away in the straights..I think even the 2.5 the S10 has started life with 100 hp from the factory, and the 2.5 iron duke has a huge aftermarket support for them.. not meaning to discourage ,,just observing. 1 Quote Link to comment
Dirttrack510 Posted April 5, 2012 Author Report Share Posted April 5, 2012 Ok, I got the A87 head installed and it fired right up. I noticed right away that is sounds much more responsive and revs up really nicely. I know pics are nice, but Videos are better, so here ya go.... http://youtu.be/WZ_QSx4GUg0 This is starting to turn into a "Video" build page. lol :D 1 Quote Link to comment
wayno Posted April 5, 2012 Report Share Posted April 5, 2012 Sounds good, have fun racing next weekend. If you can get away with a L20b at least, I would go that route, as there is no substitute for displacement, and I am sure you could get away with an L18, as I beleave it looks the same on the outside, and I am sure you opposition is doing everything they can in that area also.

Rustina 510 Posted April 5, 2012 Report Share Posted April 5, 2012 Or even a single cam Ka would have a long list of parts that can easily be added. And efi. And more horse power. This has been my favorite build and daily read lately "along with the s13 rear disc stuff going on right now" and that wagon is the shit dude. So I'm a fan :) keep the vids coming friend.

Dirttrack510 Posted April 5, 2012 Author Report Share Posted April 5, 2012 I have a complete L18 & L20, but i already have most the parts for a true, fully race prepped L16 that should SCREAM & I'm not much slower than the neons now. Quote Link to comment
Rustina 510 Posted April 5, 2012 Report Share Posted April 5, 2012 Use what you have. Run the season and if the results aren't what your looking for then make a adjustment or find a different plan of success. We can't have neons beating us, we are all counting on you. No pressure or anything... ;) Quote Link to comment
Dirttrack510 Posted April 5, 2012 Author Report Share Posted April 5, 2012 Lol, i'm workinh on it. It gets a little faster with each modification. Quote Link to comment
Dirttrack510 Posted April 5, 2012 Author Report Share Posted April 5, 2012 I'm just curious.My carb is fairly rich, so i was wondering, Would a hotter plug burn more of the fuel & make more power. I don't know shit about hotter plugs. Quote Link to comment
troyt Posted April 5, 2012 Report Share Posted April 5, 2012 Do a google search on 'plug heat', lots of good info out there. It has to do with the length of the plug tip that sticks into the combustion chamber, ie the amount of heat the ceramic tip can handle. A hotter plug will NOT cure your rich carb issues, only properly jetting your carbs for the application will fix that. Most racers have a box of carb jets for different track altitudes, different temperatures, and different states of motor tune. It takes a while to get it right, but once you do, then you can fine tune with plug heat. Keep it up, we love having another Race Wagon on the forum! Quote Link to comment
Dirttrack510 Posted April 5, 2012 Author Report Share Posted April 5, 2012 Yeah, i've been collecting jets & slowly tuning the carb. I run Pulstar plugs, with capacator discharge. about $12 a plug. Quote Link to comment
Rustina 510 Posted April 5, 2012 Report Share Posted April 5, 2012 I always hear that ngk plugs are the best for any l series engine Quote Link to comment
Dirttrack510 Posted April 6, 2012 Author Report Share Posted April 6, 2012 I'm gonna swap out the 180 main jets tonight and put in the 170 mains, then take out the 65 idle jets and put in the 50's. That should help the rich condition, then I'll run it for a night and check my plugs again. Quote Link to comment
Aaron Datsun Posted April 6, 2012 Report Share Posted April 6, 2012 Loved your first vid sorry the engine decided to do quit on you. I agree with everyone above run what you got, upgrade later. I have spent to much time with my car on the sidelines because I wanted to upgrade something that worked just fine before hand. Keep the video's coming and do us all a favor and stomp some neons next time. We're all counting on you. Quote Link to comment
