My n/a super b3 build

[bravekozak]

This is the first time I have read this thread. It took me a long time to go through it from the beginning until now. Unbelievable patience. You have inspired me to go for the finish line on my build. I still have a few small things left to do before Ohiostiva. All I can say about your build is one word. Amazing. Did you ever install that MSD blaster coil? The reason I am asking is because I have the same one.

No this cam is more extreme then the roller cam I had before. This cam is the same profile he used on his engine that put out 265 horse with the turbo

That looks like some serious money wrapped in all that aluminum! Super build!! Keep us posted

[Team Lightning]

Is the new cam the same as the one that he originally made for the motor or is it a different profile?

[drumnerd33]

Well the intake gasket came in but we just got a decent snow storm and it's cold.... Lol I don't have a garage to work in.

I got everything back from Matt, all valves were bent so all new valves, and new cam with the same grind he had on his. Built the head and was putting it altogether but the intake gasket was torn, so ordered one and they never called me so I called and they sent it back....Grrrrr so I just ordered it off of Amazon so it comes straight to me.

Any progress to report yet?

[bobstad]

wow...

Cost is really not that bad considering im going to have a full custom built basically race motor.... so matt is giving really good prices, i am more then happy with the money i spent with him plus you are giving money to another member and helping him progress the buildability of the b3 and getting amazing work.

Makes a person wonder, what could be gleaned-for a far more modest B3; from this type of full-on massage?

This is my first read through, so perhaps later in the thread someone will go in that direction...

Any updates?

Yeah and getting the cam ground to be aggressive is hard cuz the cam is weak and that's why the rollers dug into it... Matt had mine hardened also so that obviously didn't help it. And those rollers aren't built to handle a steep ramp on the cam so I'm kinda thinking that's what caused it, but can't say for sure.

Hmm, well that just sucks then. You've made me rethink making solid lifter rollers now. The plain ones are probably lighter too, and nearly nothing to go wrong with them being totally solid hunks of metal/s.

[drumnerd33]

Yeah I checked every single one and they were good, so I'm not sure if it was just the aggressive cam or it just failed... But either way I have had nothing but problems with the roller rocker set up so I'm going back to mechanical. If you look at the picture of the cam you can see the path that the rollers were running on the cam... They dug into it a little bit and it was opening up my lash and started tapping so I shimmed the lash adjusters once but started getting tapping again. So in my own opinion it's just not worth the hassle... Plus with a cam for mechanical rockers Matt is going to increase my separation to broaden my torque curve and make it more aggressive.

Woah. Did you check the rollers before they were installed? I know I checked mine and found one to be a little noisy and "lumpy". Not anything that a stock cam would probably have an issue with(not so far anyway), but maybe that's what happened here.

[drumnerd33]

Sent all the valves to Matt so he can run them in the valve machine to see if they are bent at all... All my exhaust valves hit the pistons, and looks like a few of the intake did also.

Here's what was left of the roller


And here is the lobe on the cam that hit the broken pieces, look close and you can see the indentions
