Works with race or pump gas and head no mods required.  Everything is new in the original packaging and the original manufacturers warranty applies*.

Products we sell: At bpratv our kits come with the same brand name parts as other rebuild kits you see online but we always include items no one else does.  We are a distributor for every major manufacturer in our industry and we stock the exact same parts from most of them so that when back orders occur like they have been for the last year we have an alternate part to send that is the same quality.  This would be the ONLY reason your order might be slightly different when it arrives. 

 

Returns: Please check your order completely right when you receive it and let us know immediately if there is an issue, that way we can fix it for your ASAP.  99% of problems can be easily solved without returning the entire order.  We accept returns within the first 30 days for orders sent back 100% complete and all parts brand new, never installed or prepped for installation, in the original packaging.  Once items have been installed or used in any way they are no longer eligible for return.  

 

*Warranty: We stand behind all parts we sell 100%.  If after installation there is an issue contact us for a warranty return.  Most products we sell ARE NOT DIY.  Assembling and tuning an engine is not easy and it has to be done EXACTLY RIGHT.  We send an instruction sheet with our kits that lists the steps for assembling an engine and you must follow EVERY SINGLE STEP, and do so correctly.  We ALWAYS 

STRONGLY recommend parts be installed by a qualified, experienced mechanic.  Warranty does not cover failure that is a result of improper installation, tuning, break in, or misuse.  The person who installs the parts we sell takes on a large responsibility for them working properly.  We do not refund or replace parts that have not been installed correctly.  For any warranty to be considered the part(s) in question must first be sent back to us for inspection.  We do not warranty parts based on phone calls, photos, or another mechanic's assessment alone.  FOR ANY RETURN FOR ANY REASON JUST CONTACT US FOR AN RMA AND A RETURN LABEL (IF APPLICABLE).

 

Feedback: Positive feedback is greatly appreciated.  We have changed the way we do business in response to customer concerns and receiving positive feedback when an order goes the way it is supposed to is a huge help.  If you do not feel we deserve positive feedback just contact us and we will do what is needed to help you feel as "positive" as possible about your experience.  Also, we want information from customers when their experience is less than desirable so we know what areas need improvement the most.  Please work with us and we will ALWAYS work with you.
