I have E heads on my 66 and also on my spare engine. They have been done for years and hate to take them off as they work.
Put a 455 together for a friend and used the SM heads. Light port work, hyd cam, factory HO intake. Car runs good but is just a driver. Car is a 73 SD bird and his original heads were cracked. I have a set when for when I retire my car back to street duty hopefully within the next year or so (depending if I can find another 65-67 body to build for a racecar).

Any that fit the e-heads will work on the sm heads if that was what you were
asking. GT |

Just the e-head motor It's in my firebird. The one in my avatar.
It's pretty bad ass, Haven't been to the track yet but will soon. The SM head motor is in my buddy's 4-door chevell and isn't ready yet but he is very close so as soon as I know something I'll be posting it. His car is pretty lite we are hoping for high 9's low 10's Only the track will tell. GT |

No time runs today right to first round car went 10.93@127 but my son Jake went red -.016 still very proud first car he has drag raced faster than 18.00 1990 Bonneville his grandmother gave him back in 2007. The car is a 1992 Firebird that is a very well thought out car but not tubbed and has 28-10 slicks on it. Also me being his dad and first time with a new car I had him shift at 5500

The engine is a 1970 455 + .060 good rods and pistons stock crank with the SM heads cam is a comp hydraulic roller .520/.540 236/242 113ls. I did use solid rollers I had on shelf. Intake is a SM Black Friday single plain I made match heads. Personally I would consider this engine a street engine at 10.7 and the little cam. Carb was the weak link this weekend I used a 800 spreadbore holley I had on shelf also. Probably not my greatest idea but I had it so I used it. Hopefully we will take it to the Pontiac race at Bunker Hill in two weeks with a improved carb setup.

That's a good MPH. Probably low 10's in quarter.
Was he running slicks?
