Herb's 68 Camaro Convertible
Herb called and told me his story on the tired stock 250. His engine was using oil and low on power, causing him to lose fuel mileage and the fun of driving his car. His budget did not allow rebuilding of the entire engine. I suggested a cam kit and performance cylinder head. He decided on the cylinder head. Here are his words. Remember, this motor has over 200,000 miles.
"head installed on 9-9-2013 @20778 miles. I ran castrol 20-50 for 1442 miles to check for burning, found no problems. In nov. 2013 I put in 5-40 turbo-diesel synthetic. I averaged 15-16 MPG until March 2014 and 25103 miles, when the mileage moved up to 17 MPG. Then on 5-28-2014 it moved to 18 MPG at 26773 miles where it s been for 4 tankfulls. I haven’t fooled with my Holley since last year. All this on an engine with over 200,000 miles . Not too bad, thank you Tom for the head and good advise. Herb"
The head was a 1.84/1.6 bolt in lump head. He also said his car performs better than it ever has. And the mileage is higher than it ever was. Infact, he told me people drive too slow, now.
