Been interested in some of the big naturally aspirated combos lately. What have you guys done? What's the most someone has made with a single 1050/1150? Anyone switched to a big throttle body on the same intake and made any gains?

I will report back in a month or so I had to drive 5 hours last nite to pick my block up. Had the cam tunnel bored out. Got about 5 hours of driving on Sunday to get the block to the next shop to CNC the lifter bores, install lifter bushings, CNC piston bores, hone and re-balance the motor because I just spent a small fortune on a new set of Pistons with all the fancy stuff done to them. This has been a very expensive upgrade especially when you add in my time running around, fuel and $200 citation I got in Pennsylvania. So we will see what happens on the dyno.

How much power are you aiming for?

I think it will go 950 no problem if I put some vacuum on it should be closer to 1000. Everything will be in place to pull vacuum just little nervous about it because of things I've read from people that probably don't have a clue what they are talking about or any buisness discussing it but we will see. It's alot of money and I'm by no means a big money guy cant afford to build another one.

I'm using a conventional head might I add.

Do your research on vacuum and wrist pin oiling, if your going to have extended periods of time at wide open throttle. Sounds like a cool build.

the shop i use does all of that.you could have shipped it and saved yourself a lot of driving,and the ticket.

Tunnel ram?

No problem DLC coated pins. Moly on the skirts. It's not an uncommon thing with these kinds of motors. I think the biggest thing is weeding out all the misinformation on the Internet. It's just like using a Titanium intake valve. I've even said it myself that it shouldn't be done. But it is being used has been being used with great success. But it's not accepted by the "main stream" internet voice. Should it be used in every marine engine hell no. It costs a fortune and in most applications not needed. But in the right application used properly the pros out weigh the cons and it can be used with success. Does every motor need a dry sump? No, but some do. I think I'm at that point with my combination. I think the you can't do this and you can't do that crowd does a big dis-service to the community when they really have no clue what they are talking about. I'm guilty of it. One thing I've learned getting into this project is the more I have an open mind about it the more I learn.

I may have missed it, just curious, what size motor are you building ?
