The best( and about only) example of a P7 motor drag racing on this forum was my buddies 68 Dart he raced all summer, year before last.
Wow, a little arrogant there.. Just cause I don't race asphalt, I'm not good enough to be an example??? I'm glad your BUDDY is the only one GOOD enough to be taken into consideration in this forum... Just another example of all you clicky azzholes on here... IF you don't drag race assphalt you're no good...
Last i checked this is a drag racing forum. I wasnt trying to be arrogant, just stating a fact, he actually raced one a whole season. Only person i know who has done so.
Lighten up dude, i didnt say he was good, bad or indifferent, just said he raced it, and posted his basic combo and what it ran.
Your ice racing deal has zero to do with this forum, unless they changed it from drag racing.
I have posted on here for 10 years, go pack sand.
Are you kidding me?? I know it's a drag racing forum you frickin Douche. How is drag racing on ice not drag racing??? Please tell me sir why I don't qualify? Sorry my 7 years isn't good enough for your 10.. Once again you go with I'm bigger and better then you...
And I have 3 seasons drag racing on mine... 
So now i am a douche for posting facts on a post somebody besides you started.
I can only speak for myself, but i could care less about ice racing, nothing against you, but i dont see what it has to do with this forum.
If we were going to talk about R5P7 stuff, guess we could read old Busch/Nascar forums as well, but like ice racing they dont interest me, not probably do they interest the original poster, who i am quite sure wanted to know who had drag raced a a p7 deal.
69 Dart GTS A4 Silver All steel, flat factory hood, 3360race weight
418 BPE factory replacement headed stroker, 565 lift solid cam
Best so far, 10.40 @127 1/4
1.41 best 60 foot
6.60 at 103.90 1/8

No you are a douche because you are telling me things I already know.
1. The OP asked how they are for drag racing. (I answered because I drag race)
2. You tell me this is a drag racing site. ( I know that's why I posted here.)
3. Again you proceed to tell me about drag racing and this site and the OP wanting to know about drag racing a R5P7.. ( and again I understood this before you explained to me the last 3 times, like I'm a 5 year old.)
So please sir once again I'm asking how does what I do not pertain to the OP or this site?
\
You're right, it is kinda clickish here, and I for one am a fan of ice racing. I wish they showed more of it on TV. Good luck on the asphalt! PS I'm also a fan of the bad boy small block crowd of which you are one.

All of the info posted on people's experience with this engine is relevant. Just remember opinions are opinions. What each person deems important in terms of the drag racing world is individually based. There's no need to argue or discredit one's post. I say agree to disagree and keep it moving.

The one down fall I have heard on these motors is the valve stem size and running a bigger spring pressure for bigger cam for drag racing. But I know they, valve guides can be made bigger.
I think that is the biggest down fall of these motors for drag racing. A cam change, better intake, bigger carb, a little off the head to up the compression and you can look in upwards of 1000hp. If given the time and effort you could have a killer set up.
Only issue is the limited amount of trans stuff. Jesse is the only one I know doing some sort of adapter.
When my project is a little more firm I will reveal what I am doing and let the nay sayers tear it apart.
Bondo Bob also does adaptors, My buddy used one of his and it worked flawlessly.
I am not going to run an automatic. I am actually going to row.

I think we need a group hug here  This is a RACE forum, not just drag racing. We have drag racers, ice drag racers, boat racers, truck pullers, and some roundy round guys in here. It is a forum for all RACERS. Everyone is entitiled to thier opinion and those opinions are how we learn. So let's see if we can get back on topic here please. Now dont make me get out the  Hate to see this be the first time I axe a good topic on Moparts

If you are planning on putting it in a car you will have to modify the k frame for sure. You will have to find a place to stuff a 1.5 gallon oil tank, remote filter, and (8) different size AN lines flowing everywhere. Build custom headers. Mount the motor plate and get an adapter for a trans.
I drove mine on the street for short trips with no problems as well.
true getting into a stock eng compartment will be a chore. You look like you have a nice clean installation.
I will be lucky, tube car....

An all out engine is going to cost plenty of $$$, you're not going to get any change out of $60-80K
Maybe that much in Oz with all of the shipping charges you guys have to endure, but my friend in the dragster has less than $20K in his and almost $6K was in the Engler Fuel Injection, and dry sump system. I forgot to mention, they don't have have any provision for wet-sump oiling, so dry-sump is a necessity.
Using ex Nascar pieces will save you a ton of $$$$, but I was referring to an engine from a Comp Elim style engine builder using new parts. The top end alone will eat up $10-20K. Price up a SB2.2 engine at Patterson's or Rick Watters and you will see what I mean

Here are our specs for the P7
225" tuttle FED
1370lbs total in the water
358" 3.25 stroke, 4.195 bore
296/302 @.050, 830 IN 785 EX (at the valve) 115.5 LS
*Heads are later Evernham versions with a little "massaging" for alcohol happiness by Chad Speier. Straight nascar pull offs are great with gas not enough volume for alky.
*Engler mechanical straight port injection 2.900" (He was an extreme help!)
*MSD pro mag (electronic msd 7AL-3 didn't like 10,000+)
*GRP aluminum rods. Small flat dome (.050) 14:1 Comp.
*It has been pretty much a maintenance free piece and extremely consistent. As said earlier the parts are out there some good some not so good as is the case with any engine combo. The basic engine was what we had left after hanging up our round track shoes. Also, Kent Ritter has been and still is extremely helpful with advice and or parts! So far the engine's best times are:
1.06--60'
4.69---1/8
7.40---1/4
These were at 3900' (if i remember correct, haven't run since last summer)
launch @ 7000
shift @ 9600
thru the traps @ 10400
Definitely a screamer through short zoomies!

Tube car will be great! Lots of room and super light!! Should be an easy high 8 car.

I have pretty much the same build as you. Except the injection. Looks like I should be shifting a bit higher. I was doing 1-2 at 8400 and 2-3 at 8800. My stall is 7200.. I'm gonna hit the asphalt this summer can't wait to try the higher shift points
