Whats a nice camshaft i could get for a 305. im a full on noob when it comes to what im looking for in cam shafts and what all the numbers mean. im looking for something that will be good at about 270hp nothing more. just some street performance. when i get this i plan to get a holley model 4165 and edelbrock airgap and perhaps a new set of heads.... so can anyone help me out =D

 

first- did you ever find out what was leaking?

next, here we go again. Someone with a vehicle which is at least 20 years old wanting to replace heads and valve train on a 305.

Please do a search on that question about performance and 305's and then perform a cost/benefit analysis

I assure you, between this forum and others, your question has been asked at least 6 gazillion times with the same answer given over 80% of the time (majority can't be wrong)

 

Comp cams make amazing street camshafts. I would personally go for part of the xtreme energy line-up. With the xtremes you will need to change valve springs and lifters though. This is the summitracing link to them.
COMP Cams 12-242-2 - COMP Cams Xtreme Energy Camshafts - Application - SummitRacing.com
If you dont want to be changing springs and lifters go for a thumpr cam
COMP Cams CL12-601-4 - COMP Cams Thumpr Hydraulic Flat Tappet Cam and Lifter Kits - Overview - SummitRacing.com
In my opinion i wouldnt even go to 490 with stock springs.

 

the general consensus on here and elswhere on camaros with a 305 is....burn it.all youll hear is that awful din of 350350350350350350 .go to comp cams website and get the help you are actually asking for.as for heads edelbrock makes a fine aluminum head for 305s
