Re: 548 CI BBC Advice
Different intake on the dyno, dyno distributor, standard volume Moroso pump and standard shaft. Other than the valve adjustment, nothing was really wrong on the dyno. Oil filter from dyno runs was cut open and there was not much in there, not until I put it in the car did the problems start.

Re: 548 CI BBC Advice
Had the same issue with a customers engine. After talking it over for an hour or so, I asked what filter he put on. He said Fram. I told him to go and get a K&N and call me back before he fired it again. 20 minutes later I got a call from him and I told him to fire it. Immediately had full pressure and never so much as bobbled from that day on.TBART1970 wrote:Different intake on the dyno, dyno distributor, standard volume Moroso pump and standard shaft.

I am just asking as a sanity check.

Thank you.cstraub wrote:This things does not need cams thrown at it ......it needs the issues that it has fixed. The oil contamination being the number 1. It seems that the distributor gear issue has been addressed.

The OP came on here asking for a little advise on camming, not asking for a pick a part of the entire build. Obviously per Mr. Vizard's concise and proven methods somethings could have been improved with ideal parts and rework but this OP is not looking for that at this point and he is just trying to get back to the dyno with some cam change and optimize what he has. Let's not over critique or analyse this situation here. I think all of us should just convey the idea to all new members here on Speedtalk that they should use and listen to good knowlgeable peers here and that the time to collect information and discuss choices and expectations is before they start choosing and buying parts and building their engines!!
I'll say it again " plan your work and then work your plan!"

And now we have the big guy here telling him what he will make for power down to the tenth of a horsepower, lol.. Big guy is not much help fixing the real problem with setting up the lifters and oiling issues and such. As much as advertising . Op work with straub he will try his best to set you right, and figure out your issues to the best of his abilities.

Re: 548 CI BBC Advice
TBART1970,
As so many have stated it seems like you have more problems here than just the heads I have been talking about. Although the heads, if you are hoping for a really good build, will be an issue it won't be at the moment because of all the other stuff going on. For now I will post the cylinder head stuff on my 572 thread as that has stalled due to being here. If you need anything in the way of specs to get results PM me.

Sent heads to get flowed with the intake. Decked, valve job and maybe port work.
