A cam to support that RPM would need exhaust manifolds that cost as much as your whole engine budget.

What are specs on that short block and what pistons are in it? Piston choice and piston to deck clearance as critical when doing any sort of performance build. If they are cheap builder deep dish pistons you may end up with low compression and put cam, heads, intake, etc. for higher RPM and end up with a very low power engine at any RPM. Everything must be matched to meet your goal. Typically in a wake boat you want a broad flat torque curve, not a peaky screamer that only makes power above 4 grand.

Roller cams are great in a SBF, but I thought there was a budget. The faster ramp rates that are possible can broaden the torque curve and increase peak power. Fewer worries about oil type too. Nice but really a luxury after properly matching everything else. If there's an area to spend a couple hundred more, my first choice would be forged pistons.
Ok , so my prob is if I call mabbcco engine where I plan to buy the short block what do I need to tell them ?

They have several options for their short blocks and long blocks , but I want power adders i.e. Intake, heads, and I want a good sounding cam , I guess they call it a "rough idle cam " ? Anyways

What do these 351w come with far as lifters ? Just flat tappets ? I know you gave me a parts list , but it's a bit much for my budget , I've got like 3500 for engine , PSS , shaft , prop . I mean I can always add$$ lol but I'm trying to stick with it.

I want 350 hp and 9000 lbs of torque ! Lol

So short block with GT 40 s ? Or what heads and what can with the short block ?

Here is the link : https://www.mabbcomotors.com/catalog...d_Warranty/210

They are local for me , and looks like some of the only ones for In stock short blocks . I don't know the specs but if you can list what I need to ask I certainly will .


Thanks for the help ! I'm ready to start another project for the sunsport !
