im doing the same biuld now and the CR will be 11.3to1 and with CTR pistons it will be 11.7to1 ..mine should be goin soon- ported and polished head but i dont know what cams yet, let me know how the crowers are

 

402's wont make power to 8K, neither will 403's! If you ae going to use 402's you may want to consider running nitrous with the compression you will have! Just my 2 cents!

I guess my big question is how to solve the problem of the 5500rpm drop off in the LS motor...it seems to lose its breath right around 5500-7000rpm the whole way.

Not really! Most seem to make power to 6000-6300! The cams and pistons will help with that as well as the IM since it'll allow it to pull more air in! Also with N2O you will end you making power about 600-800 rpms before you normally would without it! So with your setup you will probably find yourself shifting at 5800-6000 rpm, but dynoing will be the best way to determine that!

CTR pistons will be much higher than 11.7:1 in an LS. More like 12.5:1.

 

sell those 402, get some springs and retainers and put some 404 sticks in there

 

i like this post, its good to hear people discussing non vtec build ups

No, you are wrong. You need to learn about compression height for the PCT's and other Honda pistons. This topic has been discussed many times. That calculator is not accurate when it comes to PCT pistons.

You must change the Piston to deck height to 0.00 to get a correct reading!

I'm assuming that the timing needs a slight retard not to detonate on this high of compression?

In any case, this is sounding like a pretty strong streetable setup.

talk to arw321 about this!

 

SAVE MONEY ON MACHINE WORK!!!!!! I am selling my built b20 head with fresh machine work. The head was run for 3000 miles. Port matched and casting flash taken out. Fresh valve job, deck trued, hot tanked, and assembled with crower dual valve springs, titanium retainers, and stock valves, with bran new valve seals. all accompanied by crower 403 cams. I am selling ALL of this for 600 plus shipping or 600 picked up in socal. THIS IS A DEAL considering how much I spent on parts and labor for the machine shop. If you want pics and info click the following link.....

Looks good! And is definitely a good deal especially since Crower cams and valetrain will run you $600! Try posting this in other nonvtec threads and put an ad in your sig! Good luck!
