Im just startin out in this business but i am very good with a sbc. Ive built over 20 motors for street car and 3 for race car, that people ran for 2 years now and still hasnt rebuild them and one i buil like 3 months ago. I dont charge wild assembly fees almost 90% of your bill will be parts. The reason I started building motors is to help out the racers that arent rich, that cant afford to go to a engine building place and pay $5000. send me a message and let me know what you need. YOU WONT BE DISAPOINTED AT ALL.
