I was wondering if any of you guys know how much horsepowera 2001 4.6L engine block can withstand? Just the block not anything else.

Is there any way to find out about my block?

fruhdaddy

what about your block?

If its a windsor or romeo?

fruhdaddy

yours is most likely a windsor. do you have 11 or 13/14 valve cover bolts. They are basically the same engine just some have a 8 bolt crank instead of a 6 bolt and the water pump pulley and t-stat housing are different. They both give out the same power.

I think that the '01's up to '04's are Romeo.

fruhdaddy

some 01s were still windsor...they stopped at a certain date in 01 when the windsor plant shut down..you would have to check you vin code or valve cover bolts to be sure.

I have a late 01 I know this because I have a different water pump pully. I have been looking into the UDP by Steeda. So what you guys are saying that I can keep the block and just add the internal parts and will be good with high number of HP.
