    Cylinder head discussion 340 with stock above deck pistons

    @Inertia The Friday night street legal shoot out we participate in to do these 1/4 mile passes at mission raceway does NOT allow open headers or un muffled cars. It's a street car shootout where it's always heads up and people are just racing their cars and having fun. You can get 9 or 10 passes...

    Thanks for the input about heads, I'm also considering port matching my current j heads and doing a light blend and polish to increase a bit of flow without changing things to drastically. As for my car going faster I really need to take it to the track again and hit it harder off the line as I...

    Cylinder head discussion 340 with stock above deck pistons

    The original intent was a discussion about heads. My car is not strictly a drag car it's a street car I like to take to the strip. I don't even think most people responding to this are reading the whole thread. Seems like you are just arguing with each other and making assumptions about driving...

    I do have adjustable shocks front and rear in the car. The tire size is 235 60 15 so they aren't big tires and I've been considering adding clatracks. That being said I haven't had tire shake or jump yet off the line. It just plants and I go. This season I will be setting my 2 step up so I can...

    Maybe an xe284h would be a better cam, would have to cut the guides a beleive if it went in the stock j heads. But I would also probably need to go with 3.73 or 3.9 gears out back if I jump the cam up much

    Cylinder head discussion 340 with stock above deck pistons

    Goals for the car is just a fast street car that I take to the track. The nearest track is off the island I live on so I can't realistically get to a track more than a few times a year. Main goal is just improving speed and having a fun street car. Other things I've thought of putting on are...

    Yeah I've tuned the spray to make sure the fuel ring is in the right place and there is no black specks on the porcelain either. It seems to be at just the right spot for the spray at least. I'm gonna work on the carb this season with Inertia to try and dial it in a bit better but up till.now...

    I'm sure that I can leave harder. It was my first time on drag slicks and was working my way up in rpm to see how far before I spin. This season I will set up the 2 step so I can adjust it to the edge

    Not professionaly tuned but according to afr it seems ok? 12.6 at WOT? What's your recommendation

    Cylinder head discussion 340 with stock above deck pistons

    I find it interesting how far we have gotten from the original intent of this post. It's a question about heads. And it had turned into a bunch of guys saying that I'm slow..... like I said before a couple times. It's been down the 1/4 in one event. Of course it needs to be dialed in and I can...

    Cylinder head discussion 340 with stock above deck pistons

    You have a 360, my best 60' I posted above. It was 2.0, 1/8 8.5@86, 1/4 13.1 @ 108. I can probably shave a bit off my 60' but as I said above I've only done the 1/4 for one event. There is no track close to me anymore. So fine tuning launch rpm isn't easily available. This thread is originally...

    Cylinder head discussion 340 with stock above deck pistons

    Haven't done a no spray yet because I've only done the 1/4 at one event. There is no track close to me. My friend with similar setup and no nos runs 13.8. I launch at about 2500-3000 I'm gonna run a 2 step next time I go out and tune that. I shift about 6250 because my cam is good from 1600-5800...

    The car has 12.6 afr at WOT same afr while under spray. 37* timing before spray and down ro 34* while spraying. I tuned that off the spark plugs as maximum before you get black specks on the porcelain. I can drive...... My friend has the same setup as me with no spray and runs 13.8

    Cylinder head discussion 340 with stock above deck pistons

    I'm already spraying approximately 30% of peak power. When I hit it around 3250rpm I'm probably close to 50% don't really want to hit it much harder than that. I have jets to go to 125hp and higher. But I want to upgrade heads to for more power regardless. I think it would be a fun upgrade to do...

    2.0 60' 13.1 at 108mph im running micky street slicks 235/60r15 if I can increase horsepower and get a better 60' that would be even better. I've always wanted to get better heads and increase some power. And lower the weight on front end too
