Rock N Roll Engineering

Bruce built my motor, many years ago, 2000, and the car still runs like a bat out of hell. 455 with his ported Edelbrock heads, and driving it is amazing. So still running strong, 20 yrs later

What happens when all your research leads you in two different directions? For a Pontiac 350, can you run a set of 400 6s9 heads with the 2.12 intake valves? Do you have to chamfer the cylinder block? The pontiac engine design is a block that was essentially discontinues in 1979 (not counting the 301) and Rock & Roll still has one of the best experts who could help me with my query. I was referred to Rock and Roll Engineering because they have the record for the worlds fastest pontiac. Not expecting much in the way from a cold call, I was given more critical information in a 4 minute conversation than you could possibly cut and paste from 5 hours of internet research. I am grateful as the info likely saved me about 1000 dollars. Highly recommend this shops expertise and can attest to the customer service and respect I was given as a cold call. Thank you.
