Oversize CAM on rebuilt 302 & reduced vacuum to breaks

1965 Restomod Fastback - I lost vaccum due to the new add of a oversize CAM,I then added an additional electric vacuum pump which helped some still not that good. I hate the electric vacuum pump, way too much noise eveytime it kicks in. The brakes were upgraded to Disc in the front but the back brakes are original.

Is it difficult and costly to replace the rear brakes from Shoe to Disc and then remove the vacuum on the motor. Any leads on good mechanics close to Tacoma Wa?

Ran into this problem the same way you did, but back in '75 with a Ford 289.
First of all,and you've probably done it already, is to make CERTAIN all vacuum hoses and connections, tees etc. are leak free. Then move on to diaphram actuated valves (egr valve, heater core valve, vacuum modulator valve, distributor vacuum advance.... and then there's the diaphram actuated dampers for a/c and heat in the dash) ALSO, a good idea is to add a larger than stock vacuum canister, such as a large coffee can - metal of course!

I have no compression on my 1998 corolla what could be the problem ?

This phenomenon is called blow by. This usually happens when the engine compression escapes through the worn out piston rings due to the severely scratched cylinder wall. It also happens after the engine becomes severely overheated due to the loss of coolant or the car is driven with ruptured element air cleaner for longer period of time or due to the aging factor.
In this case the engine requires complete overhaul. It includes the replacement of the following parts to help enable the engine to perform satisfactorily as long as for many years without any problem.
The dire requirement here is to maintain the oil clearances of various parts during the machining process to ensure the reliability and dependability of the engine.
Engine parts to be replaced with original:
- Engine valves.
- Valve guides,
- Piston set (oversize).
- Ring set (oversize).
- Main and big end bearing shell set (Oversize).
- Crankshaft thrust (oversize).
- Timing belt and bearing set.
- Gasket set complete kit.
- Oil filter.
- Element air cleaner.
- Engine oil.
- Silicone RTV Grey.
- Radiator coolant.
- New valves and guides fitting and valve seat redressing.
- Valve clearance adjustment.
- Cylinder re-boring and honing.
- Crankshaft grinding, main and big end bearings fitting, and main line checking/ correction.
- Connecting rod alignment.
- Radiator cleaning and cooling system inspection.
Hope that works.

What is the difference between standard size main bearing and oversize main bearing. Which is best for the 5.4L V8 engine

thats a good un? ok standard bearings are a standard size,,,over size bearings are smaller in the center to make up for the metal that has been removed from when the bearing was re-fased
ie: ground down to smooth it off so its flat again,,,,,now you can fit oversized bearings on a standerd bearing becouse they would be far to tight and would lock the bearing up,,,,so you need to re-grind the bearing serfice or fit standerd bearings back in,,,only if the shaft is a good one?
i hope this has help you out

What is the diameter of the crankshaft supposed to be when it is ordered so I can figure out what size bearing to order?? I measured it to be 2.20 inches

When you order bearings they list them as standard or .005 oversize or .010 oversize and so on. If you are ordering a new crank it should require standard bearings. And alot of times new crankshafts come with bearings.

1964 1/2 mustang beinig rebuilt. A new 302 engine

That's because the 302 and the 260 don't share the same accessory bolt patterns. If it's a dealer installed AC the mounting may be "custom". If you still have the original engine, transfer the bolt hole positions, drill and tap. Good luck. Measure twice!
