Recommended Posts

I purchased a 68 Skylark convertible that was converted to a GS 455. Not sure if there are any Stage 1 parts on the engine now but, when I bought it I got a spare block, timming cover,crank and heads. I want to build a Stage 1 or 2 and not sure where to start. I started checking part numbers on the heads to see what the were and if they are even usable. Here is what I have so far.<BR>Part #: 1231786 (checks as a Stage one head)<BR>Part #: 1240149 have no Idea<BR>How do I know which one is left and right?<BR>Why do I ahve two different part #s?<BR>How do I know what type of block I have?<BR>I live in Fulton NY...just 20 Min North of Syracuse. Is there a good buick shop in the upstate or central NY area that may help? <BR>null

There are not lefts and rights to Buick heads, The stage 1 heads should be easy to identify by a nearly nonexistant space between the valves, If there is more then a fingernails worth of space between them they are standard heads.<P>As to why you have different numbers I have no idea. I always started with an assembled motor when beginning mods.<P>A good place to start would be a T/A performance catalog as they have the widwest range of high perf parts for Buicks.<P>They also sell complete engines for those who can't or don't want to build their own.<P>You should also look into transmissions and a better than stock rear end since even minor mods will overwhelm the stock 10 bolt, Usually leaving you stranded by the side of the road.
