more questions ............sigh*(man has this site changed) I'm starting to collect items for this 170 turbo we are building. I have most of the basic components but it's camshaft time. LOL* I have no idea where to begin even after reading every thing on this site twice. this is what I have. 1 170 block 2 198 crank 3 a well worked head that performed beyond my expectations Did really good normally aspiriated. 4 Buick T3 turbo 5 lots of other misc. turbo components you gotta have. What I need to know is a good starting point for a camshaft that will work in this mild set -up. I'm not racing here ......just want drivability and reliability,and to have some fun. sure would like to see about 360 hp and some equal torque. don't want to boost this over 9 to 10 lbs at the most more like 8..... ANYONE HAVE A BASELINE I COULD START EXPERIMENTING WITH? BTW: BEST REGARDS TO ALL maxracer |

I would go to this thread and take a look at what Oregon Cam Grinding offers. http://slantsix.org/forum/viewtopic.php?p=191616 You can mix and match whatever lobes are listed. I'm thinking the lobe from cam #819 as the intake lobe and the lobe from #818 on the exhaust ground on 114° lobe centers and advanced to about 106° intake centerline, maybe more. You'd end up with 248/240° advertised, 219/212° at .050" lift, .437/.441" lift and about .010/.012" lash. Since you're not going for a lot of boost I'd shoot for a true 8:1 static compression ratio. Wow, this cam is very much like the one Doug Dutra designed, but with wider lobe centers. http://slantsix.org/forum/viewtopic.php ... les#227653 360hp is likely going to require more boost, but this combo should idle well and pull well off the boost. |

My cam is a Erson 220* @ 50 w/ .465 lift, 114* lobe center installed at 101*. Idles like stock cam. Pulled a 370 rwhp and 23 psi with a bowl port head. Is your turbo alittle big for the 170ci? Later Ryan |

A stock cam will make good power. I estimate mine was making 450 at the crank but had about 20psi more than you are expecting to use. Joshie's cam recemendations look reasonable. Keep the LSA 114* or higher. The buick turbo migh be a little lazy for this app but should work fine. |
