I don’t know what pistons with reliefs are

Anthony, they dish out the pistons where the valves would hit the pistons. See the area circled in red on the attached photo.

Good stuff. Wouldn't pistons with reliefs be a simpler approach than tuning a tune modified VANOS?

Stick with the 288/280 for good 8300 max rpm power, is there a benfit to running higher lift cams?

In theory higher lift cams do make more power everywhere, and would probably be especially beneficial when increasing displacement.

Im thinking about Lang racing but don't u need custom pistons with higher lift cams

Carllio and JE Pistons

I think at least the "normal" duration Schricks do work with the standard pistons. The lift increase at TDC is minimal.

[M/Anthony]

Are there piston, conrod and crank questions coming or have you already selected an assembled kit?

a stroker has nothing to do with oil delivery and being starved.
VAC make a higher volume pump but I don’t think it’s necessary for a NA engine

Those cam durations are more for power north of 8000 rpm and you’d probably make better torque with less powerband compromises using the schrick 288/280 14mm cams but it’s quite a bit harder on the valve train.

With a stroker, I should be increasing oil flow to not starve my valve train, is there a way to upgrade my oil pump but not go dry sump? not worth 7K

Also, Just checked VAC's and Achilles website but Cat Cams make a 296/288 13.0mm and 12.75 lift.
This seems very optimal due to the fact that high lift will be better in for torque and power below 8300 rpm and while still having a good upper powerband?
Any opinions on this?

[M/Anthony]

Also Achilles motorsports make valve springs designed for up to 14mm lift cams,

CSL conversions are Alpha N

I thought you could just run complete CSL software and not get an alpha N tune

[jbfrancis3]

is there a detailed CSL Airbox conversion thread?
I dont want alpha N

I'll bet Fletcher (or any proven engine builder) will not do this. It's like bringing a cow to your favorite steak house.

I’m going to try and our source the majority of components myself, then just have him do some custom work, and put my bottom block together.
I’m hoping I’ll be able to consult him in my build without him making me pay, Id figure it’s around 10k for the majority of parts, the only thing I would really want him to do is block work like bore it then, balance and assemble it.
then again that may be tough, and he might not do that. I’m not trying to write out a $20k check when we can outsource and save $3k and slowly buy and add parts and just pay for one off custom parts and labor.
Everyhting should be completed and swapped into a car by December, I have time and out sourcing will just be cheaper and work better to save money and to not waste it on one big check.
i would hope someone like fletcher would understand and be ok with that, but I’ve never dealt with engine builders or much with this industry before.
