MerCruiser 470/488 engine....
What can I do to one of these little BBF headed 4 bangers...? Found one local for sale. Been thinking it would be nice in this little street rod frame I have laying around. Rat Rod power anyone???

To much power and you just break the block.
To pep-up some Sea-Ray boats we would buy a pair of Trick Flow 290 heads and use one on each engine.

I don't want to get crazy with it but my dad has this 30 street rod frame and wants to do something with it. Figured this would be a cool powerplant.

It would. Most people that saw it wouldn't have a clue what it was.

Again ... they did a pretty good job when designing the block for the power output needed so, increasing power by a lot and you will simply break the block; been there. Get compression much over 10/1 or revving it much above 5,000 RPM and you will need to find another engine.
We simply had the stock camshafts reground to just a LITTLE increase.

Thanks! I'll see if I can close the deal on this
