Strange Engine Number? Stupid tuning questions
Thanks again for the Informations.
I get crazy on searching parts in the Internet.
But i found some parts which i think they could fit.
Can you guys do me a favor and check if they really do?
Pistons:
Sealed Power
OR
Silv-O-Lite
Do i need special pistonrings for them? Or simple Oversized from Rockauto for example?
Can you recommend one of those pistons?
Do both work with Stock Connection Rods?
Are both reliable?
(I can not find total Flat-Top-Pistions on the net to buy)
Cam + Drivetrain Kit:
Comp Cam
Headers:
Clifford Header
Converter:
I have found those ones, but i do not know if you (@Moparoffical) spoke about that
TCI
BossHog
TCI 2
Thanks a lot again
Sorry for asking those stupid questions. I dont want to make a mistake and throw money away
both of those pistons are .040 over size, that may be fine, but it is usually best to have the machine shop doing the work to verify
the bore size and what it will take to clean it up prior to ordering the replacement pistons.
the Silvolite pistons that you linked have a dish on the top per the notes on the page, the Silvolite pistons that I linked are flat tops, search at Sumitt by that part number.
Either of those piston manufacturers should be fine, I have used Silvolites previously.
You will need over sized rings to match the size of the over sized pistons
The cam you linked should be fine, will be handy for you as you will be getting many components in one package and that should help on shipping.
I think that cam will be a good fit going into a heavy vehicle like a 37 Plymouth, 212 @.050 will get you good end torque, a big cam like 260 @.050 will push the power band up high in the RPM range, nice on a drag strip in a light car not good on the street in a heavy car.
For the torque converter, you need to know:
1) what rear gear you will be running,
2) approximate weight of the vehicle
3) ratios in the 904
4) have made a final cam and other engine selections, compression ratio,,,
then contact one or more of the converter manufacturers, they will have technical persons that will be able to tell what converter they
have fits your needs. If you have the converter that came with the 904 and it is from a truck application, like the motor, you can consider
using the converter as is. I would spend that money on having a good shop go through the 904 and making sure it is in good working order first.
Consider a mild shift kit for the transmission to firm up the shifts, get a nice floor mounted shifter...run that for a while, then if you think a different stall speed is needed work with one the converter companies
oh yea, and concerning the exhaust header, I would wait until you have mounted the motor in the engine bay before making any decisions on the header.
Yours is a very custom install, it will be difficult to guess which exhaust routing would be best, or even fit. Kind of pricy, but another option is Dutra Duals, they are sourced from Austrailia, heavy cast iron, but something to consider.
