Any of you out there have any experience with the engine rebuild kits that are floating around? I have a 305 and saw suddenly on E-bay a 305 Engine master rebuild kit. It was around $300 and was brand named engine tech. Did a little searching and found their website here. So my questions is does anyone have experience with engine build kits or specifically this brand. Any thing you can tell me about them like what brand is best what the quality is for engine tech or what a better quality brand is out there. Thanks.
