**Customer Review of Our Pontiac 461**
 

Here are some pictures of my car and engine compartment. I bought the 461 Pontiac stroker 475 H.P. and you were right, this engine is just what this car needed, awesome power, sound and looks. The engine has a big lumpy idle ( which is what I really wanted ) and sounds really good thru my exhaust system.
I also have the 3" electric dumps, talk about a nice sound, believe me I get everybody's attention, what an awesome motor. Thanks so much for doing such a great job building my motor, it looks and sounds fantastic . I will recommend your company to all.

Thanks again & again
