r5 p7 power glide adapters and flex plate

Why shift at only 7800?

My guess would be consistency and easier on valve train. I've met Mike and his family, they truly are good people! Bethany is a hell of a driver and the Duster has been a winning ride for some time.

Hopefully the guy who's got the old combo can get it to run just as good as you had it running Mike! .......

Any pics of the car and engine?

No sure how its making that much power down low?? Is it a short track engine?

I agree. Most ive seen makes peak power around 8800rpms

My buddy had an r5 p7 in his 3000 pound dart and he only shifted it at 7800 or so.
Ran high 5's low 9.40's
Was a restrictor plate motor.
12 to 1 and the cam was only 248/258@50.
So I am not surprised a 400 pound lighter car is running those numbers at that rpm.
Those little motors make lots of steam. He had his heads flowed at a very reputable shop and they inched over 400 cfm.
Best bang for the buck out there.

Mike,
It's time to remove that BB in the dragster and drop in a R5P7. Then we won't have to scramble looking to prime that pump all the time, lol.

I have over 400 runs on my r5p7 and it hasn't so much as loosened the lash by .001. It's truly a waste of energy to remove the valve cover and look......nothing changes.

Oh, and if you guys are curious, I buzz the sh@#$ out of my motor 9000+ every run. Just ask any announcer at any big dollar bracket race. That little 358 out runs most 582 chevies on the back half as well ( 143.5 @ 660' and 178.5 @ 1320)

Guys, the moral of the story is......quit whining about how nascar motors don't do this or can't do that.......PUT YOUR CARS ON A DIET and ET's will improve drastically.

Mike

I wish I had went with these engines years ago.

I don't need to call jw sense I already have flexplates made. If you read my post you can see we have a sfi 30.1 bell to go behind these engines and use Reid cases. No sheilds, adapters, or any tricks. Just bolt it in and go. Should have on display at QuickTime booth and race parts liquidators.

We actually shifted it at 8600 for half the season and was trying to slow the car down a little so we short shifted it at 7800 and it ran exactly the same so we have just left it there.it has been 1.19 in 60 ft,leaving at 5200.It has a 1.80 low gear glide,15x33-15 tires,probably would be faster with smaller tire too. If i can figure out how to post a picture i will get it on here shortly.

540 is out and for sale,i ordered the plates to put r5 in yesterday,so we should be ready for new years race.

I cant wait to see it.



Mike will you have it ready for the Hang over race at Montgomery?

Sorry to go off topic alittle but what gas are you useing for these motors?
Mine came with sunoco premium witch is 115 octan i cant see that being needed at only 12-1?

Sunoco 112 blue due to rpm. A lower rpm could run 110 purple.

Probably overkill but I use VP C14 since i'm cranking it 9000+

Thanks. Think e85 would work?

The engine is a takeout, nothing done to it,has a Ron's terminator alky injection, glide trans with 180 gearset, 5.67 rear gear, but only runs 3 hundredths slower with 4.56 in 1/8th mile.Tires are 15-33-15.

Awsome!!!

What is the converter?

Fti. Ss895b-2

Talked with Eric from JW at PRI. He could not remember the exact spacing on his flywheel. He gave me a figure but it does not sound correct if you run starter spacers. Do you run washers to correct converter pump engagement or have any motor plate spacing built into converter?

The reason I ask, is no sense in two companies making the same flexplate. My next run of bells I may deal with JW. The price they quoted was $375 for flywheel and crank converter adapter. Does this sound correct?
