Smile P-30 Hedders

I went with the Hooker Hedders they were 185.00 in the door I'll make sure that everything hanging behind them is
supported by hangers. I hope the 700R4 tranny is going to be strong enough it's totally rebuilt with 13 clutches and I'll probably install a cooler also the coach is only 24 ft long. I was towed up Monte Eagle Mountain by a 4WD Toyota p/u a few years back when the distrubutor decided to die he got up to 40mph w/o using the 4WD. I have taken some pictures and I'll try to post them after I getr done. So far I have about 4k in the whole project and it should be much stronger the old 454 had over 100k miles on it. Also I am putting new pwr steering pump water pump new distributor ceramic plug wires had the radiator cleaned repainted pressure checked. About the only thing I'm using from the old engine is the NAPA
starter and I had purchased a cast Iron starter nose a guy
had made for drag car engines so I hope I am making this thing bullet proof!!

Hello,
I have installed quite a few 700R4's. They are very sensitve to heat and proper shift points. Make sure you adjust the kick down with a pressure gage. Go to Bowtie Overdrives who specialize in 700R4's, Hesperia, CA on the web. I have used their system with no issues. I have used 5 of their transmissions on jprojects with no issues even behind big blocks with 550HP.

Cooling will be paramount for this trans. I normally omit the radiator pass thru and use 2 after market coolers the biggest you can fit. This trans hates heat. I am going to try to go to a higher temperature fluid such a 5 or 6 on a current project we have. It does not break down as standard fluid does. I would also suggest a cool tube pan and a trans temperature gage. This will tell the story. I have heard horror stories on towing with a 700R4. If you tow very little it should work with good cooling. Make sure your converter locks up at the lowest RPM you can get as slipping causes heat also.

Thanks for the Input Chris, I hope I made a good choice on the tranny. the extra clutches should help it out but I will make sure she stays cool. on the pan you suggested is that a pan that has cooling fins on the bottom? This is a 79 model so no computer and the kickdown is operated by a cable I don't want to work on this thing any more after I get it back in one peice. just want to drive and enjoy it. about the only thing I might tow with it is a
4X8 trailer with a golf cart on it. I plan mainly to travel to
Bluegrass Festivals and Pick my dobro!

Wink Big Dog Movin IN

Well the old dog is out and the new dogs a movin in the old 454 came out fighting kicking and screeming fought me every step of the way but I finally won the battle. I did have to pull the oil pan and pump from under the coach
I want to put the new dog back in with the oil pan installed and it looks as if
I will have to grind off two rivets in the top of the very front cross member
that protects the brake equalizer valve, remove the two bottom bolts and loosen clamps that hold brake lines in place then find a large shoe horne to squeeze her in place. Anybody out there that has accomplished monumental feat please feel free to chime in and say yeah or nay. That front door is mighty short for a big dog 454 and the chains must be very short to the intake manifold or the intake should be off while putting him in the house. I have not done this before and information is a preimum. So far I have done this with no help from anyone other that those that say I am crazy to spend the $$ for a new engine on a 28 year old coach. But you folks know how it is!
She's my Baby, I don't mean maybe I'm never gonna let her go !!
Thanks in bunches if any real mantic mechanics out there wish to share their secrets for smooth installin

The absolutley best headers are DOUG THORELY , once you have held a thorely header in your hands and seen the quality and the heavy gage of the steel and the 3/8 thick flange (header to the cylinder head) you will want a set .most aftermarket headers are low cost cheaply made .The summit
truck headers on my p-30 and p40 chassis could not handle the heat ,they crack ,fairly fast ,the thorelys have been on my p-30 mobile auto /truck RV ,service truck ,they are in excellent condition after
7 years now driving it 6 days a week .Don't go cheap ,just buy the best ,
you will not regret it ,you get what you pay for .Headers by doug ,by the way are NOT Doug thorely headers ,so ask for them by name .

I would have to disagree. I just put on the Banks header (with the 5/8 flange) and are extremely pleased. I didn't gomwith the power pack due to the costs, but ordered the headers which came with all mounting hardware and heat shields, and the cold air intake. The coach already had factory dual exhaust, so I had a local muffler shop weld the existing pipes to the new header flanges. Saved alot of money. Banks also included a transmission kit which adjusted the shift points to work with the new performance levels. Great system!!!

1987 345 Tell me more about the cost involved in what you purchased from Banks. This is the way I am leaning and I would like to know more. Figured a fellow Texan would lay it on me like it is.

Did'nt get the Banks Headers, but invested about $ 700 in mufflers, tailpipes, hangers, & exhaust pipe repairs. Maybe later on the Banks.
