couple items here for your engine needs First up is a Seal kit meant for sealing engines for long term storage. Bags are fine for short term but will never hold up for very long. Everything in the kit is 10ga. steel except for the lift plate which is 1/4". Not pictured is a plastic plug for the distributor hole. SBC, Exhaust port seals, water pump and water neck seal, fuel pump block off and lift plate. Fuel pump block off is heavy enough to use as a permanent block off when switching to an electric fuel pump. Kit cost as pictured (unpainted) with the plastic dist. plug is $25.00 plus shipping. Kits for other engines will be developed. Second item is a Engine balance plate. You'll need one of these if your building a 383 or 406 externally balance but using the small 350 flexplate. I'm not an engine builder but Coonie's Racing engines that moved into the shop this past fall has been working with me to get these out so here they are. Made of 13ga. Cold rolled steel. $9.00 plus shipping.
