427 Valvetrain parts
What does nearly $8k buy these days... I hope it performs as good as it looks.
not shown are the new buckets, valve locks, and shims to set the spring heights. Last edited by tpepmeie; 12-03-2010 at 02:23 PM. Reason: math error... |

Dang that's pretty!
Are the spring seats any different than stock?

Re: 427 Valvetrain parts

Re: 427 Valvetrain parts
Who builds 427's? As in who not as in why build a 427. I would love a 427, much more than a 415.

Re: 427 Valvetrain parts
Not as big as you might think... only 39.5mm. plenty of room in the chamber to go bigger, up to 42mm. You have to be careful of valve clash between the intake & exhaust if you have significant lift around TDC. Next time, I'll go bigger....

Re: 427 Valvetrain parts
Todd,
You've clearly spent a great deal of time, planning and money on this project. What's your expectations? How will you be judging whether you've succeeded and that money was well spent? |

great question. What does success look like... 1) I actually get it assembled in time for the dyno test in January... 2) starts up with no drama... 3) good compression, ring seal, etc. 4) at least 700 chp on the engine dyno 5) no infant mortality, the thing survives the dyno test without wiping a cam lobe or breaking something. 6) no smoke, minimal oil consumption We'll see. Recent experiences by some of the other members have made me a little quesy about turning the key first time. After all, this is the first time I've assembled an LT5... Todd |
