Re: Can I use (stock) Ford 351C HEADS on my Ford 302 ('79) Block

The windsor heads return coolant through the intake and not the block like Cleveland. The 351m and 400 blocks are 10.29 deck so you would have to cut if even possible to fit 8.2 302. Its totally possible. Cometic head gaskets solve the water flow issues. He drilled the 302 block for 1/2" head bolts...

Wow. Thanks Graig. Interesting I have been using delvac MX or Cat DEO in my light common rail engines. But I change it at 8000km. I hate black oil.

Re: Best oil for 6.7 Cummins

I have had better results in my big diesels with Delvac...better oil samples with higher TBN numbers after a 50,000 mile oil change interval. Lucas and Schaeffer are very good, too. Rotella always fell short. Are you referring to delvac 1 full synthetic? 50000 is a long time for oil to be in an eng...

Re: Valve lift vs. port flow and cam selection

If you dont have any numbers how in the world to you even know what to grind? Thats an odd question, Its pretty rare/unlikely that in a high effort build you would have no numbers at all. I cant see anyone building anything competitive not having any numbers at all. As has been said time again, num...

Re: single compression ring piston

I have done 3 Kawasaki Z900/1000 big bore engines using 2 ring pistons. Worked well in the applications 2 were street bikes. No oil issues, no compression issues.
But smaller bore than you're looking at.

Re: Flat Plane V8 Race Engine - Single Exit Exhaust Question

Hi, with one bank number odd and the other even (1-3-5-7 front to back N/S and 2-4-6-8 front to back O/S) the firing order is 1-4-5-2-7-6-3-8 So essentially if it were a 4 cylinder it would fire 1-3-4-2 on both sides Given that firing sequence you would pair cyls 1&3 , 5&7 ,,, then 2&8 , 4&6.

Re: oil ring support rails / some quests

The oil support ring in most cases needs to be the full depth(or just less than) of the oil ring groove It needs to be a good fit and will need to be expanded from its natural position to correctly fit the piston. It needs to spring back/reduce in diameter so that it is snug in the bottom of the rin...

Re: Flat Plane V8 Race Engine - Single Exit Exhaust Question

For some reason it was in my mind that your were restricted to runnint 2.5 collector and tailpipe! I read back and realise that is not so. In that case then yes, 2.25 collectors are fine, then into the 2.5 tailpipe. The headers must be right though, you can not run a tight exhaust system with oversi...
