Low oil pressure

[silverfox]

My oil pressure keep getting low,so i pulled the motor yesterday.Got the oil pan and main caps off today.My main bearings are shot and mess my crank up,the motor does not have alot of pass on it ( its a drag car ) so i am thinking about going with a stroker motor.I have been looking and there are a couple of different combos 393,410 418,427,446 and 454 all small blocks.Does anyone run any of these.I would like to go big but big is not always better.What do you think. :3gears:

That sux man...only 4 mths to go. gonna have to get something figured out....how about sticking that 302 with the windsor heads back in with a couple turbos or a supercharger??? Already got the motor just need the other stuff and i'm sure Shane L. can hook u up with a couple turbos...

[silverfox]

Yea four month to go but i will have it ready.Turbo sounds nice but i am going to stick with big inch motor and alittle nos or alot.LOL

Any thoughts on what hurt the bearings?

[silverfox]

I,m not sure everthing check out good when i put it together.I had alot of work done on the block dont know if something didnt go right.I,m going to have it check out.

size of motor depends on what you want to do with your ride.......full race....some street?

[silverfox]

Its full race.

I will take any advice on what inch motor would be best.

A better question might be how much of a budget do you have for it?

There's no single answer to whats best. Will it have to fit into any certain class or just grudge racing type deal?

Its a bracket car footbrake.I would like to go low 6,s on motor i have a little budget to work from.

You can do it with less cubes but you'll need more compression and rpms.


I'd say at least a 408-434ci. As those can stil be done with a stock block.
Somewhere around 11:1 or more if you don't mind buying race gas. (my 427 is 10.75:1) All forged. Light weight internals will help. Forged I beam rods,short compression height pistons (heavier stuff if a nitrous setup)

At least some 225cc intake runner heads or larger

Solid roller with .650-.700 lift 260 ish duration or more if the compression is above 11:1 106-108 center line if always on motor 110-112 if a nitrous setup

Super Victor intake,850 cfm carb

2" primary headers,3.5 collectors,etc

If its no more than 3000-3100 lbs that should run 6.2-6.4 on motor.

Were the mains studded and/or girdled on your old block? Sounds like a possible cap walk issue......look on the surfaces of your caps and block registers (where the cap sits) and see if theres any shiny spots and/or pits on one surface, and buildup on the corresponding surface. Either that or a bad line none job...but that wouldve showed up when you checked your bearing clearances....what were they by the way?

As for a stroker...well.... the longer that arm, the harder itll be on parts if you intend to wind it tight. CI = torque, RPMS = hp
If it was mine and all motor, id go 393 or 408 with a loose converter, nasty gear, and wind it up. (NC stang guys post above- hes right on the money!) Or you could go with big CI, tighten the converter, and add a small plate system for a brutal torque monster.
Then again, if you have cubic dollars, you could build the holy grail.....434+ CI AND turn it 7500+:thumbsup1:
