    SP03 is rated 1.5 out of 5 by 2.
    Rated 2 out of 5 by from OIL USER I bought this engine for my truck about 5-6 months ago. Put in my roller valvetrain and and put on big valve aluminum heads and intake / carb. I broke it in VERY CAREFULLY. 1st oil change at 500 miles. This engine runs well but uses oil. Never smokes but the tailgate of my beautiful truck is oily after 100 miles. One quart for every 600 - 700 miles. No leaks. Excellent oil pressure. VERY DISAPPOINTED with oil usage. Wouldn't recommend this reman to anyone.

    Rated 1 out of 5 by from Ok,I am a little disappointed because the pitcher shows flattop pistons and I got dish. I have never rebuilt a motor with dish pistons. Sorry but I am not happy.

    Would the middle thumper cam fit without any valve issues hitting piston?

    Hello, this is something you would have to measure. Typically anything under 230 duration @50 is ok.

    Is this a Vortec ,1 pc rear main seal,roller cam motor, are they flat top pistons ?

    Asked by: Hummingbird 1
    Hello, this is a 1pc seal dished piston engine. The term "Vortec" refers to the cylinder heads. We also have a flat top version of this short block under part number SP04. Both engines can be used with OE roller cam setups.
